General Description
General Description
Micron NAND Flash devices include an asynchronous data interface for high-performance I/O operations. These devices use a highly multiplexed 8-bit bus (DQx) to transfer
commands, address, and data. There are five control signals used to implement the asynchronous data interface: CE#, CLE, ALE, WE#, and RE#. Additional signals control
hardware write protection (WP#) and monitor device status (R/B#).
This Micron NAND Flash device additionally includes a synchronous data interface for
high-performance I/O operations. When the synchronous interface is active, WE# becomes CLK and RE# becomes W/R#. Data transfers include a bidirectional data strobe
(DQS).
A target is the unit of memory accessed by a chip enable signal. A target contains one or
more NAND Flash die. A NAND Flash die is the minimum unit that can independently
execute commands and report status. A NAND Flash die, in the ONFI specification, is
referred to as a logical unit (LUN). For further details, see Device and Array Organization.

Architecture
These devices use NAND Flash electrical and command interfaces. Data, commands,
and addresses are multiplexed onto the same pins and received by I/O control circuits.
The commands received at the I/O control circuits are latched by a command register
and are transferred to control logic circuits for generating internal signals to control device operations. The addresses are latched by an address register and sent to a row
decoder to select a row address, or to a column decoder to select a column address.
Data is transferred to or from the NAND Flash memory array, byte by byte, through a
data register and a cache register.
The NAND Flash memory array is programmed and read using page-based operations
and is erased using block-based operations. During normal page operations, the data
and cache registers act as a single register. During cache operations, the data and cache
registers operate independently to increase data throughput.

1. CAx = column address, PAx = page address, BAx = block address, LAx = LUN address; the
page address, block address, and LUN address are collectively called the row address.
2. When using the synchronous interface, CA0 is forced to 0 internally; one data cycle always returns one even byte and one odd byte.
3. Column addresses 4320 (10E0h) through 8191 (1FFFh) are invalid, out of bounds, do not
exist in the device, and cannot be addressed.
4. BA[8] is the plane-select bit:
Plane 0: BA[8] = 0
Plane 1: BA[8] = 1
5. LA0 is the LUN-select bit. It is present only when two LUNs are shared on the target;
otherwise, it should be held LOW.
LUN 0: LA0 = 0
LUN 1: LA0 = 1

Asynchronous Enable/Standby
A chip enable (CE#) signal is used to enable or disable a target. When CE# is driven
LOW, all of the signals for that target are enabled. With CE# LOW, the target can accept
commands, addresses, and data I/O. There may be more than one target in a NAND
Flash package. Each target is controlled by its own chip enable; the first target (Target 0)
is controlled by CE#; the second target (if present) is controlled by CE2#, etc.
A target is disabled when CE# is driven HIGH, even when the target is busy. When disabled, all of the target's signals are disabled except CE#, WP#, and R/B#. This functionality is also known as CE# "Don't Care". While the target is disabled, other devices can
utilize the disabled NAND signals that are shared with the NAND Flash.
A target enters low-power standby when it is disabled and is not busy. If the target is
busy when it is disabled, the target enters standby after all of the die (LUNs) complete
their operations. Standby helps reduce power consumption.
Asynchronous Bus Idle
A target's bus is idle when CE# is LOW, WE# is HIGH, and RE# is HIGH.
During bus idle, all of the signals are enabled except DQS, which is not used when the
asynchronous interface is active. No commands, addresses, and data are latched into
the target; no data is output.

Asynchronous Data Output
Data can be output from a die (LUN) if it is in a READY state. Data output is supported
following a READ operation from the NAND Flash array. Data is output from the cache
register of the selected die (LUN) to DQ[7:0] on the falling edge of RE# when CE# is
LOW, ALE is LOW, CLE is LOW, and WE# is HIGH.
If the host controller is using a tRC of 30ns or greater, the host can latch the data on the
rising edge of RE# (see Figure 17 for proper timing). If the host controller is using a tRC
of less than 30ns, the host can latch the data on the next falling edge of RE# (see Figure 18 (page 28) for extended data output (EDO) timing).
Using the READ STATUS ENHANCED (78h) command prevents data contention following an interleaved die (multi-LUN) operation. After issuing the READ STATUS ENHANCED (78h) command, to enable data output, issue the READ MODE (00h) command.
Data output requests are typically ignored by a die (LUN) that is busy (RDY = 0); however, it is possible to output data from the status register even when a die (LUN) is busy by
first issuing the READ STATUS (70h) or READ STATUS ENHANCED (78h) command.

Write Protect
The write protect# (WP#) signal enables or disables PROGRAM and ERASE operations
to a target. When WP# is LOW, PROGRAM and ERASE operations are disabled. When
WP# is HIGH, PROGRAM and ERASE operations are enabled.
It is recommended that the host drive WP# LOW during power-on until Vcc and Vccq
are stable to prevent inadvertent PROGRAM and ERASE operations (see Device Initialization (page 41) for additional details).
WP# must be transitioned only when the target is not busy and prior to beginning a
command sequence. After a command sequence is complete and the target is ready,
WP# can be transitioned. After WP# is transitioned, the host must wait tWW before issuing a new command.
The WP# signal is always an active input, even when CE# is HIGH. This signal should
not be multiplexed with other signals.
Ready/Busy#
The ready/busy# (R/B#) signal provides a hardware method of indicating whether a target is ready or busy. A target is busy when one or more of its die (LUNs) are busy
(RDY = 0). A target is ready when all of its die (LUNs) are ready (RDY = 1). Because each
die (LUN) contains a status register, it is possible to determine the independent status
of each die (LUN) by polling its status register instead of using the R/B# signal (see Status Operations (page 65) for details regarding die (LUN) status).
This signal requires a pull-up resistor, Rp, for proper operation. R/B# is HIGH when the
target is ready, and transitions LOW when the target is busy. The signal's open-drain

driver enables multiple R/B# outputs to be OR-tied. Typically, R/B# is connected to an
interrupt pin on the system controller (see Figure 19 (page 29)).
The combination of Rp and capacitive loading of the R/B# circuit determines the rise
time of the R/B# signal. The actual value used for Rp depends on the system timing requirements. Large values of Rp cause R/B# to be delayed significantly. Between the 10to 90-percent points on the R/B# waveform, the rise time is approximately two time
constants (TC).
TC = R × C
Where R = Rp (resistance of pull-up resistor), and C = total capacitive load.
The fall time of the R/B# signal is determined mainly by the output impedance of the
R/B# signal and the total load capacitance. Approximate Rp values using a circuit load
of 100pF are provided in Figure 24 (page 32).

Bus Operation – Synchronous Interface
These NAND Flash devices have two interfaces—a synchronous interface for fast data
I/O transfer and an asynchronous interface that is backward compatible with existing
NAND Flash devices.
The NAND Flash command protocol for both the asynchronous and synchronous interfaces is identical. However, there are some differences betweeen the asynchronous and
synchronous interfaces when issuing command, address, and data I/O cycles using the
NAND Flash signals.
When the synchronous interface is activated on a target (see Activating Interfaces
(page 42)), the target is capable of high-speed DDR data transfers. Existing signals are
redefined for high-speed DDR I/O. The WE# signal becomes CLK. DQS is enabled. The
RE# signal becomes W/R#. CLK provides a clock reference to the NAND Flash device.
The direction of DQS and DQ[7:0] is controlled by the W/R# signal. When the W/R# signal is latched HIGH, the controller is driving the DQ bus and DQS. When the W/R# is
latched LOW, the NAND Flash is driving the DQ bus and DQS.
The synchronous interface bus modes are summarized below.

Synchronous Enable/Standby
In addition to the description in the section Asynchronous Enable/Standby (page 23),
the following requirements also apply when the synchronous interface is active.
Before enabling a target, CLK must be running and ALE and CLE must be LOW. When
CE# is driven LOW, all of the signals for the selected target are enabled. The target is not
enabled until tCS completes; the target's bus is then idle.
A target enters low-power standby when it is disabled and is not busy. If the target is
busy when it is disabled, the target enters standby after all of the die (LUNs) complete
their operations.
Synchronous Bus Idle/Driving
A target's bus is idle or driving when CLK is running, CE# is LOW, ALE is LOW, and CLE
is LOW.
The bus is idle when W/R# transitions HIGH and is latched by CLK. During the bus idle
mode, all signals are enabled; DQS and DQ[7:0] are inputs. No commands, addresses,
or data are latched into the target; no data is output. When entering the bus idle mode,
the host must wait a minimum of tCAD before changing the bus mode. In the bus idle
mode, the only valid bus modes supported are: bus driving, command, address, and
DDR data input.
The bus is driving when W/R# transitions LOW and is latched by CLK. During the bus
driving mode, all signals are enabled; DQS is LOW and DQ[7:0] is driven LOW or HIGH,
but no valid data is output. Following the bus driving mode, the only valid bus modes
supported are bus idle and DDR data output.

Synchronous Commands
A command is written from DQ[7:0] to the command register on the rising edge of CLK
when CE# is LOW, ALE is LOW, CLE is HIGH, and W/R# is HIGH.
After a command is latched—and prior to issuing the next command, address, or

Device Initialization
Device Initialization
Micron NAND Flash devices are designed to prevent data corruption during power transitions. VCC is internally monitored. (The WP# signal supports additional hardware
protection during power transitions.) When ramping VCC and VCCQ, use the following
procedure to initialize the device:
1. Ramp VCC.
2. Ramp VCCQ. VCCQ must not exceed VCC.
3. The host must wait for R/B# to be valid and HIGH before issuing RESET (FFh) to
any target (see Figure 30). The R/B# signal becomes valid when 50µs has elapsed
since the beginning the VCC ramp, and 10µs has elapsed since VCCQ reaches VCCQ
(MIN) and VCC reaches VCC (MIN).
4. If not monitoring R/B#, the host must wait at least 100µs after VCCQ reaches VCCQ
(MIN) and VCC reaches VCC (MIN). If monitoring
R/B#, the host must wait until R/B# is HIGH.
5. The asynchronous interface is active by default for each target. Each LUN draws
less than an average of 10mA (IST) measured over intervals of 1ms until the RESET
(FFh) command is issued.
6. The RESET (FFh) command must be the first command issued to all targets (CE#s)
after the NAND Flash device is powered on. Each target will be busy for tPOR after
a RESET command is issued. The RESET busy time can be monitored by polling
R/B# or issuing the READ STATUS (70h) command to poll the status register.
7. The device is now initialized and ready for normal operation.
At power-down, VCCQ must go LOW, either before, or simultaneously with, VCC going
LOW.

Activating Interfaces
Activating Interfaces
After performing the steps under Device Initialization (page 41), the asynchronous interface is active for all targets on the device.
Each target's interface is independent of other targets, so the host is responsible for
changing the interface for each target.
If the host and NAND Flash device, through error, are no longer using the same interface, then steps under Activating the Asynchronous Interface are performed to resynchronize the interfaces.
To activate the asynchronous NAND interface, once the synchronous interface is active,
the following steps are repeated for each target:
1. The host pulls CE# HIGH, disables its input to CLK, and enables its asynchronous
interface.
2. The host pulls CE# LOW and issues the RESET (FFh) command, using an asynchronous command cycle.
3. R/B# goes LOW for tRST.
4. After tITC, and during tRST, the device enters the asynchronous NAND interface.
READ STATUS (70h) and READ STATUS ENHANCED (78h) are the only commands that can be issued.
5. After tRST, R/B# goes HIGH. Timing mode feature address (01h), subfeature parameter P1 is set to 00h, indicating that the asynchronous NAND interface is active
and that the device is set to timing mode 0.
For further details, see Reset Operations.
Activating the Synchronous Interface
To activate the synchronous NAND Flash interface, the following steps are repeated for
each target:
1. Issue the SET FEATURES (EFh) command.
2. Write address 01h, which selects the timing mode.
3. Write P1 with 1Xh, where "X" is the timing mode used in the synchronous interface (see Configuration Operations).
4. Write P2–P4 as 00h-00h-00h.
5. R/B# goes LOW for tITC. The host should pull CE# HIGH. During tITC, the host
should not issue any type of command, including status commands, to the NAND
Flash device.
6. After tITC, R/B# goes HIGH and the synchronous interface is enabled. Before pulling CE# LOW, the host should enable the clock.

RESET (FFh)
The RESET (FFh) command is used to put a target into a known condition and to abort
command sequences in progress. This command is accepted by all die (LUNs), even
when they are busy.
When FFh is written to the command register, the target goes busy for tRST. During
the selected target (CE#) discontinues all array operations on all die (LUNs). All
pending single- and multi-plane operations are cancelled. If this command is issued
while a PROGRAM or ERASE operation is occurring on one or more die (LUNs), the data
may be partially programmed or erased and is invalid. The command register is cleared
and ready for the next command. The data register and cache register contents are invalid.
tRST,
If the RESET (FFh) command is issued when the synchronous interface is enabled, the
target's interface is changed to the asynchronous interface and the timing mode is set
to 0. The RESET (FFh) command can be issued asynchronously when the synchronous
interface is active, meaning that CLK does not need to be continuously running when
CE# is transitioned LOW and FFh is latched on the rising edge of CLK. After this command is latched, the host should not issue any commands during tITC. After tITC, and
during or after tRST, the host can poll each LUN's status register.
If the RESET (FFh) command is issued when the asynchronous interface is active, the
target's asynchronous timing mode remains unchanged. During or after tRST, the host
can poll each LUN's status register.

READ ID (90h)
The READ ID (90h) command is used to read identifier codes programmed into the target. This command is accepted by the target only when all die (LUNs) on the target are
idle.
Writing 90h to the command register puts the target in read ID mode. The target stays
in this mode until another valid command is issued.
When the 90h command is followed by a 00h address cycle, the target returns a 5-byte
identifier code that includes the manufacturer ID, device configuration, and part-specific information.
After the 90h and address cycle are written to the target, the host enables data output
mode to read the identifier information. When the asynchronous interface is active, one
data byte is output per RE# toggle. When the synchronous interface is active, one data
byte is output per rising edge of DQS when ALE and CLE are HIGH; the data byte on the
falling edge of DQS is identical to the data byte output on the previous rising edge of DQS.

Configuration Operations
The SET FEATURES (EFh) and GET FEATURES (EEh) commands are used to modify the
target's default power-on behavior. These commands use a one-byte feature address to
determine which subfeature parameters will be read or modified. Each feature address
(in the 00h to FFh range) is defined in Table 8. The SET FEATURES (EFh) command
writes subfeature parameters (P1-P4) to the specified feature address. The GET FEATURES command reads the subfeature parameters (P1-P4) at the specified feature
address.
Unless otherwise specifed, the values of the feature addresses do not change when RESET (FFh, FCh) is issued by the host.

SET FEATURES (EFh)
The SET FEATURES (EFh) command writes the subfeature parameters (P1-P4) to the
specified feature address to enable or disable target-specific features. This command is
accepted by the target only when all die (LUNs) on the target are idle.
Writing EFh to the command register puts the target in the set features mode. The target stays in this mode until another command is issued.
The EFh command is followed by a valid feature address as specified in Table 8. The
host waits for tADL before the subfeature parameters are input. When the asynchronous interface is active, one subfeature parameter is latched per rising edge of WE#.
When the synchronous interface is active, one subfeature parameter is latched per rising edge of DQS. The data on the falling edge of DQS should be identical to the
subfeature parameter input on the previous rising edge of DQS. The device is not required to wait for the repeated data byte before beginning internal actions.
After all four subfeature parameters are input, the target goes busy for tFEAT. The READ
STATUS (70h) command can be used to monitor for command completion.
Feature address 01h (timing mode) operation is unique. If SET FEATURES is used to
modify the interface type, the target will be busy for tITC. See Activating Interfaces
(page 42) for details.

GET FEATURES (EEh)
The GET FEATURES (EEh) command reads the subfeature parameters (P1-P4) from the
specified feature address. This command is accepted by the target only when all die

When the EEh command is followed by a feature address, the target goes busy for
tFEAT. If the READ STATUS (70h) command is used to monitor for command completion, the READ MODE (00h) command must be used to re-enable data output mode.
During and prior to data output, use of the READ STATUS ENHANCED (78h) command
is prohibited.
After tFEAT completes, the host enables data output mode to read the subfeature parameters. When the asynchronous interface is active, one data byte is output per RE#
toggle. When the synchronous interface is active, one subfeature parameter is output
per DQS toggle on rising or falling edge of DQS.

READ PARAMETER PAGE (ECh)
READ PARAMETER PAGE (ECh)
The READ PARAMETER PAGE (ECh) command is used to read the ONFI parameter
page programmed into the target. This command is accepted by the target only when
all die (LUNs) on the target are idle.
Writing ECh to the command register puts the target in read parameter page mode. The
target stays in this mode until another valid command is issued.
When the ECh command is followed by an 00h address cycle, the target goes busy for
tR. If the READ STATUS (70h) command is used to monitor for command completion,
the READ MODE (00h) command must be used to re-enable data output mode. Use of
the READ STATUS ENHANCED (78h) command is prohibited while the target is busy
and during data output.
A minimum of three copies of the parameter page are stored in the device. Each parameter page is 256 bytes. If desired, the CHANGE READ COLUMN (05h-E0h) command
can be used to change the location of data output. Use of the CHANGE READ COLUMN
ENHANCED (06h-E0h) command is prohibited.
The READ PARAMETER PAGE (ECh) output data can be used by the host to configure
its internal settings to properly use the NAND Flash device. Parameter page data is static per part, however the value can be changed through the product cycle of NAND
Flash. The host should interpret the data and configure itself accordingly.

After tR completes, the host enables data output mode to read the parameter page.
When the asynchronous interface is active, one data byte is output per RE# toggle.
When the synchronous interface is active, one data byte is output for each rising or falling edge of DQS.

READ UNIQUE ID (EDh)
READ UNIQUE ID (EDh)
The READ UNIQUE ID (EDh) command is used to read a unique identifier programmed
into the target. This command is accepted by the target only when all die (LUNs) on the
target are idle.
Writing EDh to the command register puts the target in read unique ID mode. The target stays in this mode until another valid command is issued.
When the EDh command is followed by a 00h address cycle, the target goes busy for tR.
If the READ STATUS (70h) command is used to monitor for command completion, the
READ MODE (00h) command must be used to re-enable data output mode.
Sixteen copies of the unique ID data are stored in the device. Each copy is 32 bytes. The
first 16 bytes of a 32-byte copy are unique data, and the second 16 bytes are the complement of the first 16 bytes. The host should XOR the first 16 bytes with the second 16
bytes. If the result is 16 bytes of FFh, then that copy of the unique ID data is correct. In
the event that a non-FFh result is returned, the host can repeat the XOR operation on a
subsequent copy of the unique ID data. If desired, the CHANGE READ COLUMN (05hE0h) command can be used to change the data output location. Use of the CHANGE
READ COLUMN ENHANCED (06h-E0h) command is prohibited.

After tR completes, the host enables data output mode to read the unique ID. When the
asynchronous interface is active, one data byte is output per RE# toggle. When the synchronous interface is active, two data bytes are output, one byte for each rising or
falling edge of DQS.

Status Operations
Status Operations
Each die (LUN) provides its status independently of other die (LUNs) on the same target through its 8-bit status register.
After the READ STATUS (70h) or READ STATUS ENHANCED (78h) command is issued,
status register output is enabled. The contents of the status register are returned on
DQ[7:0] for each data output request.
When the asynchronous interface is active and status register output is enabled,
changes in the status register are seen on DQ[7:0] as long as CE# and RE# are LOW; it is
not necessary to toggle RE# to see the status register update.
When the synchronous interface is active and status register output is enabled, changes
in the status register are seen on DQ[7:0] as long as CE# and W/R# are LOW and ALE
and CLE are HIGH. DQS also toggles while ALE and CLE are HIGH.
The READ STATUS (70h) command returns the status of the most recently selected die
(LUN). To prevent data contention during or following an interleaved die (multi-LUN)
operation, the host must enable only one die (LUN) for status output by using the READ
STATUS ENHANCED (78h) command (see Interleaved Die (Multi-LUN) Operations
(page 100)).

This bit is set if the previous operation on the selected die (LUN) failed. This

Pass/Fail (N):

This bit is set if the most recently finished operation on the selected die

PROGRAM-, ERASE-, and COPYBACK PROGRAM-series operations (80h-10h,
80h-15h, 60h-D0h, 85h-10h). This bit is not valid following a READ-series
operation.
1. After a multi-plane operation begins, the FAILC and FAIL bits are ORed together for the
active planes when the READ STATUS (70h) command is issued. After the READ STATUS
ENHANCED (78h) command is issued, the FAILC and FAIL bits reflect the status of the
plane selected.
READ STATUS (70h)
The READ STATUS (70h) command returns the status of the last-selected die (LUN) on
a target. This command is accepted by the last-selected die (LUN) even when it is busy
(RDY = 0).
If there is only one die (LUN) per target, the READ STATUS (70h) command can be used
to return status following any NAND command.
In devices that have more than one die (LUN) per target, during and following interleaved die (multi-LUN) operations, the READ STATUS ENHANCED (78h) command
must be used to select the die (LUN) that should report status. In this situation, using
the READ STATUS (70h) command will result in bus contention, as two or more die
(LUNs) could respond until the next operation is issued. The READ STATUS (70h) command can be used following all single die (LUN) operations.
If following a multi-plane operation, regardless of the number of LUNs per target, the
READ STATUS (70h) command indicates an error occurred (FAIL = 1), use the READ
STATUS ENHANCED (78h) command—once for each plane—to determine which plane
operation failed.

READ STATUS ENHANCED (78h)
The READ STATUS ENHANCED (78h) command returns the status of the addressed die
(LUN) on a target even when it is busy (RDY = 0). This command is accepted by all die
(LUNs), even when they are BUSY (RDY = 0).
The selected LUN's status is returned when the host requests data output. The RDY and
ARDY bits of the status register are shared for all of the planes of the selected die (LUN).
The FAILC and FAIL bits are specific to the plane specified in the row address.
The READ STATUS ENHANCED (78h) command also enables the selected die (LUN) for
data output. To begin data output following a READ-series operation after the selected
die (LUN) is ready (RDY = 1), issue the READ MODE (00h) command, then begin data
output. If the host needs to change the cache register that will output data, use the
CHANGE READ COLUMN ENHANCED (06h-E0h) command after the die (LUN) is
ready (see CHANGE READ COLUMN ENHANCED (06h-E0h) (page 69)).
Use of the READ STATUS ENHANCED (78h) command is prohibited during the poweron RESET (FFh) command and when OTP mode is enabled. It is also prohibited following some of the other reset, identification, and configuration operations. See individual
operations for specific details.

Writing 78h to the command register, followed by three row address cycles containing
the page, block, and LUN addresses, puts the selected die (LUN) into read status mode.
The selected die (LUN) stays in this mode until another valid command is issued. Die

Column Address Operations
Column Address Operations
The column address operations affect how data is input to and output from the cache
registers within the selected die (LUNs). These features provide host flexibility for managing data, especially when the host internal buffer is smaller than the number of data
bytes or words in the cache register.
When the asynchronous interface is active, column address operations can address any
byte in the selected cache register.
When the synchronous interface is active, column address operations are aligned to
word boundaries (CA0 is forced to 0), because as data is transferred on DQ[7:0] in twobyte units.
The CHANGE READ COLUMN (05h-E0h) command changes the column address of the
selected cache register and enables data output from the last selected die (LUN). This
command is accepted by the selected die (LUN) when it is ready (RDY = 1; ARDY = 1). It
is also accepted by the selected die (LUN) during CACHE READ operations
(RDY = 1; ARDY = 0).
Writing 05h to the command register, followed by two column address cycles containing the column address, followed by the E0h command, puts the selected die (LUN)
into data output mode. After the E0h command cycle is issued, the host must wait at
least tCCS before requesting data output. The selected die (LUN) stays in data output
mode until another valid command is issued.
In devices with more than one die (LUN) per target, during and following interleaved
die (multi-LUN) operations, the READ STATUS ENHANCED (78h) command must be
issued prior to issuing the CHANGE READ COLUMN (05h-E0h). In this situation, using
the CHANGE READ COLUMN (05h-E0h) command without the READ STATUS ENHANCED (78h) command will result in bus contention, as two or more die (LUNs)
could output data.

CHANGE READ COLUMN ENHANCED (06h-E0h)
The CHANGE READ COLUMN ENHANCED (06h-E0h) command enables data output
on the addressed die’s (LUN’s) cache register at the specified column address. This command is accepted by a die (LUN) when it is ready (RDY = 1; ARDY = 1).
Writing 06h to the command register, followed by two column address cycles and three
row address cycles, followed by E0h, enables data output mode on the address LUN’s
cache register at the specified column address. After the E0h command cycle is issued,
the host must wait at least tCCS before requesting data output. The selected die (LUN)
stays in data output mode until another valid command is issued.
In devices with more than one die (LUN) per target, after all of the die (LUNs) on the
target are ready (RDY = 1), the CHANGE READ COLUMN ENHANCED (06h-E0h) command can be used following an interleaved die (multi-LUN) read operation. Die (LUNs)
that are not addressed are deselected to avoid bus contention.
In devices with more than one die (LUN) per target, during interleaved die (multi-LUN)
operations where more than one or more die (LUNs) are busy (RDY = 1; ARDY = 0 or
RDY = 0; ARDY = 0), the READ STATUS ENHANCED (78h) command must be issued to
the die (LUN) to be selected prior to issuing the CHANGE READ COLUMN ENHANCED

command without the READ STATUS ENHANCED (78h) command will result in bus
contention, as two or more die (LUNs) could output data.
If there is a need to update the column address without selecting a new cache register
or LUN, the CHANGE READ COLUMN (05h-E0h) command can be used instead.

CHANGE ROW ADDRESS (85h)
The CHANGE ROW ADDRESS (85h) command changes the row address (block and
page) where the cache register contents will be programmed in the NAND Flash array.
It also changes the column address of the selected cache register and enables data input
on the specified die (LUN). This command is accepted by the selected die (LUN) when
it is ready (RDY = 1; ARDY = 1). It is also accepted by the selected die (LUN) during
cache programming operations (RDY = 1; ARDY = 0).
The CHANGE ROW ADDRESS (85h) command is allowed after the required address cycles are specified, but prior to the final command cycle (10h, 11h, 15h) of the following
commands while data input is permitted: PROGRAM PAGE (80h-10h), PROGRAM PAGE
MULTI-PLANE (80h-11h), PROGRAM PAGE CACHE (80h-15h), COPYBACK PROGRAM
(85h-10h), and COPYBACK PROGRAM MULTI-PLANE (85h-11h). When used with these
commands, the LUN address and plane select bits are required to be identical to the
LUN address and plane select bits originally specified.
The CHANGE ROW ADDRESS (85h) command enables the host to modify the original
page and block address for the data in the cache register to a new page and block address.
In devices that have more than one die (LUN) per target, the CHANGE ROW ADDRESS
(85h) command can be used with other commands that support interleaved die (multiLUN) operations.
The CHANGE ROW ADDRESS (85h) command can be used with the CHANGE READ
COLUMN (05h-E0h) or CHANGE READ COLUMN ENHANCED (06h-E0h) commands
to read and modify cache register contents in small sections prior to programming
cache register contents to the NAND Flash array. This capability can reduce the amount
of buffer memory used in the host controller.
To modify the cache register contents in small sections, first issue a PAGE READ
(00h-30h) or COPYBACK READ (00h-35h) operation. When data output is enabled, the
host can output a portion of the cache register contents. To modify the cache register
contents, issue the 85h command, the column and row addresses, and input the new
data. The host can re-enable data output by issuing the 11h command, waiting tDBSY,
and then issuing the CHANGE READ COLUMN (05h-E0h) or CHANGE READ COLUMN
ENHANCED (06h-E0h) command. It is possible toggle between data output and data
input multiple times. After the final CHANGE ROW ADDRESS (85h) operation is complete, issue the 10h command to program the cache register to the NAND Flash array.

Write 85h to the command register. Then write two column address cycles and three
row address cycles. This updates the page and block destination of the selected plane
for the addressed LUN and puts the cache register into data input mode. After the fifth
address cycle is issued the host must wait at least tCCS before inputting data. The selected LUN stays in data input mode until another valid command is issued. Though data
input mode is enabled, data input from the host is optional. Data input begins at the
column address specified.

Read Operations
Read Operations
Read operations are used to copy data from the NAND Flash array of one or more of the
planes to their respective cache registers and to enable data output from the cache registers to the host through the DQ bus.
Read Operations
The READ PAGE (00h-30h) command, when issued by itself, reads one page from the
NAND Flash array to its cache register and enables data output for that cache register.
During data output the following commands can be used to read and modify the data
in the cache registers: CHANGE READ COLUMN (05h-E0h) and CHANGE ROW ADDRESS (85h).
Read Cache Operations
To begin a read page cache sequence, begin by reading a page from the NAND Flash
array to its corresponding cache register using the READ PAGE (00h-30h) command.
R/B# goes LOW during tR and the selected die (LUN) is busy (RDY = 0, ARDY = 0). After
tR (R/B# is HIGH and RDY = 1, ARDY = 1), issue either of these commands:
• READ PAGE CACHE SEQUENTIAL (31h)—copies the next sequential page from the
NAND Flash array to the data register
• READ PAGE CACHE RANDOM (00h-31h)—copies the page specified in this command from the NAND Flash array (any plane) to its corresponding data register
After the READ PAGE CACHE-series (31h, 00h-31h) command has been issued, R/B#
goes LOW on the target, and RDY = 0 and ARDY = 0 on the die (LUN) for tRCBSY while
the next page begins copying data from the array to the data register. After tRCBSY,
R/B# goes HIGH and the die’s (LUN’s) status register bits indicate the device is busy
with a cache operation (RDY = 1, ARDY = 0). The cache register becomes available and
the page requested in the READ PAGE CACHE operation is transferred to the data register. At this point, data can be output from the cache register, beginning at column
address 0. The CHANGE READ COLUMN (05h-E0h) command can be used to change
the column address of the data output by the die (LUN).
After outputting the desired number of bytes from the cache register, either an additional READ PAGE CACHE-series (31h, 00h-31h) operation can be started or the READ
PAGE CACHE LAST (3Fh) command can be issued.
If the READ PAGE CACHE LAST (3Fh) command is issued, R/B# goes LOW on the target, and RDY = 0 and ARDY = 0 on the die (LUN) for tRCBSY while the data register is
copied into the cache register. After tRCBSY, R/B# goes HIGH and RDY = 1 and
ARDY = 1, indicating that the cache register is available and that the die (LUN) is ready.
Data can then be output from the cache register, beginning at column address 0. The
CHANGE READ COLUMN (05h-E0h) command can be used to change the column address of the data being output.
For READ PAGE CACHE-series (31h, 00h-31h, 3Fh), during the die (LUN) busy time,
tRCBSY, when RDY = 0 and ARDY = 0, the only valid commands are status operations
(70h, 78h) and RESET (FFh, FCh). When RDY = 1 and ARDY = 0, the only valid commands during READ PAGE CACHE-series (31h, 00h-31h) operations are status opera-

To increase data throughput, the READ PAGE CACHE-series (31h, 00h-31h) commands
can be used to output data from the cache register while concurrently copying a page
from the NAND Flash array to the data register.

tions (70h, 78h), READ MODE (00h), READ PAGE CACHE-series (31h, 00h-31h),
CHANGE READ COLUMN (05h-E0h), and RESET (FFh, FCh).
Multi-Plane Read Operations
Multi-plane read page operations improve data throughput by copying data from more
than one plane simultaneously to the specified cache registers. This is done by prepending one or more READ PAGE MULTI-PLANE (00h-32h) commands in front of the READ
PAGE (00h-30h) command.
When the die (LUN) is ready, the CHANGE READ COLUMN ENHANCED (06h-E0h) command determines which plane outputs data. During data output, the following commands can be used to read and modify the data in the cache registers: CHANGE READ
COLUMN (05h-E0h) and CHANGE ROW ADDRESS (85h). See Multi-Plane Operations
for details.
Multi-plane read cache operations can be used to output data from more than one
cache register while concurrently copying one or more pages from the NAND Flash array to the data register. This is done by prepending READ PAGE MULTI-PLANE
(00h-32h) commands in front of the PAGE READ CACHE RANDOM (00h-31h) command.
To begin a multi-plane read page cache sequence, begin by issuing a MULTI-PLANE
READ PAGE operation using the READ PAGE MULTI-PLANE (00h-32h) and READ PAGE
(00h-30h) commands. R/B# goes LOW during tR and the selected die (LUN) is busy
(RDY = 0, ARDY = 0). After tR (R/B# is HIGH and RDY = 1, ARDY = 1), issue either of
these commands:
• READ PAGE CACHE SEQUENTIAL (31h)—copies the next sequential page from the
previously addressed planes from the NAND Flash array to the data registers.
• READ PAGE MULTI-PLANE (00h-32h) commands, if desired, followed by the READ
PAGE CACHE RANDOM (00h-31h) command—copies the pages specified from the
NAND Flash array to the corresponding data registers.
After the READ PAGE CACHE-series (31h, 00h-31h) command has been issued, R/B#
goes LOW on the target, and RDY = 0 and ARDY = 0 on the die (LUN) for tRCBSY while
the next pages begin copying data from the array to the data registers. After tRCBSY,
R/B# goes HIGH and the LUN’s status register bits indicate the device is busy with a
cache operation (RDY = 1, ARDY = 0). The cache registers become available and the pages requested in the READ PAGE CACHE operation are transferred to the data registers.
Issue the CHANGE READ COLUMN ENHANCED (06h-E0h) command to determine
which cache register will output data. After data is output, the CHANGE READ COLUMN ENHANCED (06h-E0h) command can be used to output data from other cache
registers. After a cache register has been selected, the CHANGE READ COLUMN (05hE0h) command can be used to change the column address of the data output.
After outputting data from the cache registers, either an additional MULTI-PLANE
READ CACHE-series (31h, 00h-31h) operation can be started or the READ PAGE CACHE
LAST (3Fh) command can be issued.
If the READ PAGE CACHE LAST (3Fh) command is issued, R/B# goes LOW on the target, and RDY = 0 and ARDY = 0 on the die (LUN) for tRCBSY while the data registers are
copied into the cache registers. After tRCBSY, R/B# goes HIGH and RDY = 1 and ARDY =
1, indicating that the cache registers are available and that the die (LUN) is ready. Issue
the CHANGE READ COLUMN ENHANCED (06h-E0h) command to determine which

cache register will output data. After data is output, the CHANGE READ COLUMN ENHANCED (06h-E0h) command can be used to output data from other cache registers.
After a cache register has been selected, the CHANGE READ COLUMN (05h-E0h) command can be used to change the column address of the data output.
For READ PAGE CACHE-series (31h, 00h-31h, 3Fh), during the die (LUN) busy time,
tRCBSY, when RDY = 0 and ARDY = 0, the only valid commands are status operations
(70h, 78h) and RESET (FFh, FCh). When RDY = 1 and ARDY = 0, the only valid commands during READ PAGE CACHE-series (31h, 00h-31h) operations are status operations (70h, 78h), READ MODE (00h), multi-plane read cache-series (31h, 00h-32h,
00h-31h), CHANGE READ COLUMN (05h-E0h, 06h-E0h), and RESET (FFh, FCh).
See Multi-Plane Operations for additional multi-plane addressing requirements.
The READ MODE (00h) command disables status output and enables data output for
the last-selected die (LUN) and cache register after a READ operation (00h-30h,
00h-35h) has been monitored with a status operation (70h, 78h). This command is accepted by the die (LUN) when it is ready (RDY = 1, ARDY = 1). It is also accepted by the
die (LUN) during READ PAGE CACHE (31h, 3Fh, 00h-31h) operations
(RDY = 1 and ARDY = 0).
In devices that have more than one die (LUN) per target, during and following interleaved die (multi-LUN) operations, the READ STATUS ENHANCED (78h) command
must be used to select only one die (LUN) prior to issuing the READ MODE (00h) command. This prevents bus contention.

READ PAGE (00h-30h)
The READ PAGE (00h–30h) command copies a page from the NAND Flash array to its
respective cache register and enables data output. This command is accepted by the die
(LUN) when it is ready (RDY = 1, ARDY = 1).
To read a page from the NAND Flash array, write the 00h command to the command
register, the write five address cycles to the address registers, and conclude with the 30h
command. The selected die (LUN) will go busy (RDY = 0, ARDY = 0) for tR as data is
transferred.
To determine the progress of the data transfer, the host can monitor the target's R/B#
signal or, alternatively, the status operations (70h, 78h) can be used. If the status operations are used to monitor the LUN's status, when the die (LUN) is ready
(RDY = 1, ARDY = 1), the host disables status output and enables data output by issuing
the READ MODE (00h) command. When the host requests data output, output begins
at the column address specified.
In devices that have more than one die (LUN) per target, during and following interleaved die (multi-LUN) operations the READ STATUS ENHANCED (78h) command
must be used to select only one die (LUN) prior to the issue of the READ MODE (00h)
command. This prevents bus contention.
The READ PAGE (00h-30h) command is used as the final command of a multi-plane
read operation. It is preceded by one or more READ PAGE MULTI-PLANE (00h-32h)
commands. Data is transferred from the NAND Flash array for all of the addressed
planes to their respective cache registers. When the die (LUN) is ready
(RDY = 1, ARDY = 1), data output is enabled for the cache register linked to the plane
addressed in the READ PAGE (00h-30h) command. When the host requests data output,
output begins at the column address last specified in the READ PAGE (00h-30h) command. The CHANGE READ COLUMN ENHANCED (06h-E0h) command is used to
enable data output in the other cache registers. See Multi-Plane Operations for additional multi-plane addressing requirements.

The READ PAGE CACHE SEQUENTIAL (31h) command can be used to cross block boundaries. If the READ PAGE CACHE SEQUENTIAL (31h) command is issued after the last
page of a block is read into the data register, the next page read will be the next logical
block in the plane which the 31h command was issued. Do not issue the READ PAGE
CACHE SEQUENTIAL (31h) to cross die (LUN) boundaries. Instead, issue the READ
PAGE CACHE LAST (3Fh) command.
If the READ PAGE CACHE SEQUENTIAL (31h) command is issued after a MULTIPLANE READ PAGE operation (00h-32h, 00h-30h), the next sequential pages are read
into the data registers while the previous pages can be output from the cache registers.
After the die (LUN) is ready (RDY = 1, ARDY = 0), the CHANGE READ COLUMN ENHANCED (06h-E0h) command is used to select which cache register outputs data.

from the array to the cache register for the addressed plane. During tDBSY, the only valid commands are status operations (70h, 78h) and reset commands (FFh, FCh). Following tDBSY, to continue the MULTI-PLANE READ operation, the only valid commands
are status operations (70h, 78h), READ PAGE MULTI-PLANE (00h-32h), READ PAGE
(00h-30h), and READ PAGE CACHE RANDOM (00h-31h).
Additional READ PAGE MULTI-PLANE (00h-32h) commands can be issued to queue
additional planes for data transfer.
If the READ PAGE (00h-30h) command is used as the final command of a MULTIPLANE READ operation, data is transferred from the NAND Flash array for all of the
addressed planes to their respective cache registers. When the die (LUN) is ready
(RDY = 1, ARDY = 1), data output is enabled for the cache register linked to the plane
addressed in the READ PAGE (00h-30h) command. When the host requests data output,
it begins at the column address specified in the READ PAGE (00h-30h) command. To
enable data output in the other cache registers, use the CHANGE READ COLUMN ENHANCED (06h-E0h) command. Additionally, the CHANGE READ COLUMN (05h-E0h)
command can be used to change the column address within the currently selected plane.
If the READ PAGE CACHE SEQUENTIAL (31h) is used as the final command of a MULTIPLANE READ CACHE operation, data is copied from the previously read operation from
each plane to each cache register and then data is transferred from the NAND Flash
array for all previously addressed planes to their respective data registers. When the die
(LUN) is ready (RDY = 1, ARDY = 0), data output is enabled. The CHANGE READ COLUMN ENHANCED (06h-E0h) command is used to determine which cache register
outputs data first. To enable data output in the other cache registers, use the CHANGE
READ COLUMN ENHANCED (06h-E0h) command. Additionally, the CHANGE READ
COLUMN (05h-E0h) command can be used to change the column address within the

Program Operations
Program Operations
Program operations are used to move data from the cache or data registers to the
NAND array of one or more planes. During a program operation the contents of the
cache and/or data registers are modified by the internal control logic.
Within a block, pages must be programmed sequentially from the least significant page
address to the most significant page address (i.e. 0, 1, 2, 3, …). Programming pages out
of order within a block is prohibited.
Program Operations
The PROGRAM PAGE (80h-10h) command, when not preceded by the PROGRAM PAGE
MULTI-PLANE (80h-11h) command, programs one page from the cache register to the
NAND Flash array. When the die (LUN) is ready (RDY = 1, ARDY = 1), the host should
check the FAIL bit to verify that the operation has completed successfully.
The PROGRAM PAGE CACHE (80h-15h) command can be used to improve program operation system performance. When this command is issued, the die (LUN) goes busy
(RDY = 0, ARDY = 0) while the cache register contents are copied to the data register,
and the die (LUN) is busy with a program cache operation (RDY = 1, ARDY = 0. While
the contents of the data register are moved to the NAND Flash array, the cache register
is available for an additional PROGRAM PAGE CACHE (80h-15h) or PROGRAM PAGE
(80h-10h) command.
For PROGRAM PAGE CACHE-series (80h-15h) operations, during the die (LUN) busy
times, tCBSY and tLPROG, when RDY = 0 and ARDY = 0, the only valid commands are
status operations (70h, 78h) and reset (FFh, FCh). When RDY = 1 and ARDY = 0, the only
valid commands during PROGRAM PAGE CACHE-series (80h-15h) operations are status operations (70h, 78h), PROGRAM PAGE CACHE (80h-15h), PROGRAM PAGE
(80h-10h), CHANGE WRITE COLUMN (85h), CHANGE ROW ADDRESS (85h), and reset
(FFh, FCh).
Multi-Plane Program Operations
The PROGRAM PAGE MULTI-PLANE (80h-11h) command can be used to improve program operation system performance by enabling multiple pages to be moved from the
cache registers to different planes of the NAND Flash array. This is done by prepending
one or more PROGRAM PAGE MULTI-PLANE (80h-11h) commands in front of the PROGRAM PAGE (80h-10h) command. See Multi-Plane Operations for details.
Multi-Plane Program Cache Operations
The PROGRAM PAGE MULTI-PLANE (80h-11h) command can be used to improve program cache operation system performance by enabling multiple pages to be moved
from the cache registers to the data registers and, while the pages are being transferred
from the data registers to different planes of the NAND Flash array, free the cache registers to receive data input from the host. This is done by prepending one or more

when it is ready (RDY = 1, ARDY = 1). It is also accepted by the die (LUN) when it is busy
with a PROGRAM PAGE CACHE (80h-15h) operation (RDY = 1, ARDY = 0).
To input a page to the cache register and move it to the NAND array at the block and
page address specified, write 80h to the command register. Unless this command has
been preceded by a PROGRAM PAGE MULTI-PLANE (80h-11h) command, issuing the
80h to the command register clears all of the cache registers' contents on the selected
target. Then write five address cycles containing the column address and row address.
Data input cycles follow. Serial data is input beginning at the column address specified.
At any time during the data input cycle the CHANGE WRITE COLUMN (85h) and
CHANGE ROW ADDRESS (85h) commands may be issued. When data input is complete, write 10h to the command register. The selected LUN will go busy
(RDY = 0, ARDY = 0) for tPROG as data is transferred.
In devices that have more than one die (LUN) per target, during and following interleaved die (multi-LUN) operations, the READ STATUS ENHANCED (78h) command
must be used to select only one die (LUN) for status output. Use of the READ STATUS
(70h) command could cause more than one die (LUN) to respond, resulting in bus contention.
The PROGRAM PAGE (80h-10h) command is used as the final command of a multiplane program operation. It is preceded by one or more PROGRAM PAGE MULTIPLANE (80h-11h) commands. Data is transferred from the cache registers for all of the

by using the status operations (70h, 78h). See Multi-Plane Operations for multi-plane

PROGRAM PAGE CACHE (80h-15h)
To input a page to the cache register to move it to the NAND array at the block and page
address specified, write 80h to the command register. Unless this command has been
preceded by a PROGRAM PAGE MULTI-PLANE (80h-11h) command, issuing the 80h to
the command register clears all of the cache registers' contents on the selected target.
Then write five address cycles containing the column address and row address. Data
input cycles follow. Serial data is input beginning at the column address specified. At
any time during the data input cycle the CHANGE WRITE COLUMN (85h) and
CHANGE ROW ADDRESS (85h) commands may be issued. When data input is complete, write 15h to the command register. The selected LUN will go busy
(RDY = 0, ARDY = 0) for tCBSY to allow the data register to become available from a
previous program cache operation, to copy data from the cache register to the data register, and then to begin moving the data register contents to the specified page and
block address.
To determine the progress of tCBSY, the host can monitor the target's R/B# signal or,
alternatively, the status operations (70h, 78h) can be used. When the LUN’s status
shows that it is busy with a PROGRAM CACHE operation (RDY = 1, ARDY = 0), the host
should check the status of the FAILC bit to see if a previous cache operation was successful.
If, after tCBSY, the host wants to wait for the program cache operation to complete, without issuing the PROGRAM PAGE (80h-10h) command, the host should monitor ARDY
until it is 1. The host should then check the status of the FAIL and FAILC bits.
In devices with more than one die (LUN) per target, during and following interleaved
die (multi-LUN) operations, the READ STATUS ENHANCED (78h) command must be
used to select only one die (LUN) for status output. Use of the READ STATUS (70h) command could cause more than one die (LUN) to respond, resulting in bus contention.
The PROGRAM PAGE CACHE (80h-15h) command is used as the final command of a

PROGRAM PAGE MULTI-PLANE 80h-11h
To input a page to the cache register and queue it to be moved to the NAND Flash array
at the block and page address specified, write 80h to the command register. Unless this
command has been preceded by a PROGRAM PAGE MULTI-PLANE (80h-11h) command, issuing the 80h to the command register clears all of the cache registers' contents on the selected target. Write five address cycles containing the column address
and row address; data input cycles follow. Serial data is input beginning at the column
address specified. At any time during the data input cycle, the CHANGE WRITE COLUMN (85h) and CHANGE ROW ADDRESS (85h) commands can be issued. When data
input is complete, write 11h to the command register. The selected die (LUN) will go
busy (RDY = 0, ARDY = 0) for tDBSY.
To determine the progress of tDBSY, the host can monitor the target's R/B# signal or,
alternatively, the status operations (70h, 78h) can be used. When the LUN's status
shows that it is ready (RDY = 1), additional PROGRAM PAGE MULTI-PLANE (80h-11h)
commands can be issued to queue additional planes for data transfer. Alternatively, the
PROGRAM PAGE (80h-10h) or PROGRAM PAGE CACHE (80h-15h) commands can be
issued.
When the PROGRAM PAGE (80h-10h) command is used as the final command of a multiplane program operation, data is transferred from the cache registers to the NAND
Flash array for all of the addressed planes during tPROG. When the die (LUN) is ready
(RDY = 1, ARDY = 1), the host should check the status of the FAIL bit for each of the
planes to verify that programming completed successfully.
When the PROGRAM PAGE CACHE (80h-15h) command is used as the final command
of a MULTI-PLANE PROGRAM CACHE operation, data is transferred from the cache
registers to the data registers after the previous array operations finish. The data is then
moved from the data registers to the NAND Flash array for all of the addressed planes.
This occurs during tCBSY. After tCBSY, the host should check the status of the FAILC bit
for each of the planes from the previous program cache operation, if any, to verify that
programming completed successfully.

Copyback Operations
Copyback Operations
COPYBACK operations make it possible to transfer data within a plane from one page to
another using the cache register. This is particularly useful for block management and
wear leveling.
To prevent bit errors from accumulating over multiple COPYBACK operations, it is recommended that the host read the data out of the cache register after the COPYBACK
READ (00h-35h) completes prior to issuing the COPYBACK PROGRAM (85h-10h) command. The CHANGE READ COLUMN (05h-E0h) command can be used to change the
column address. The host should check the data for ECC errors and correct them. When
the COPYBACK PROGRAM (85h-10h) command is issued, any corrected data can be input. The CHANGE ROW ADDRESS (85h) command can be used to change the column
address.
It is not possible to use the COPYBACK operation to move data from one plane to another or from one die (LUN) to another. Instead, use a READ PAGE (00h-30h) or COPYBACK READ (00h-35h) command to read the data out of the NAND, and then use a
PROGRAM PAGE (80h-10h) command with data input to program the data to a new
plane or die (LUN).
Between the COPYBACK READ (00h-35h) and COPYBACK PROGRAM (85h-10h) commands, the following commands are supported: status operations (70h, 78h), and
column address operations (05h-E0h, 06h-E0h, 85h). Reset operations (FFh, FCh) can
be issued after COPYBACK READ (00h-35h), but the contents of the cache registers on
the target are not valid.
In devices which have more than one die (LUN) per target, once the COPYBACK READ
(00h-35h) is issued, interleaved die (multi-LUN) operations are prohibited until after
the COPYBACK PROGRAM (85h-10h) command is issued.
Multi-Plane Copyback Operations
Multi-plane copyback read operations improve read data throughput by copying data
simultaneously from more than one plane to the specified cache registers. This is done
by prepending one or more READ PAGE MULTI-PLANE (00h-32h) commands in front
of the COPYBACK READ (00h-35h) command.
The COPYBACK PROGRAM MULTI-PLANE (85h-11h) command can be used to further
system performance of COPYBACK PROGRAM operations by enabling movement of
multiple pages from the cache registers to different planes of the NAND Flash array.
This is done by prepending one or more COPYBACK PROGRAM (85h-11h) commands
in front of the COPYBACK PROGRAM (85h-10h) command. See Multi-Plane Operations
for details.

The COPYBACK operation is a two-step process consisting of a COPYBACK READ
(00h-35h) and a COPYBACK PROGRAM (85h-10h) command. To move data from one
page to another on the same plane, first issue the COPYBACK READ (00h-35h) command. When the die (LUN) is ready (RDY = 1, ARDY = 1), the host can transfer the data
to a new page by issuing the COPYBACK PROGRAM (85h-10h) command. When the die
(LUN) is again ready (RDY = 1, ARDY = 1), the host should check the FAIL bit to verify
that this operation completed successfully.

The COPYBACK READ (00h-35h) command is functionally identical to the READ PAGE

See READ PAGE (00h-30h) (page 76) for further details.
Though it is not required, it is recommended that the host read the data out of the device to verify the data prior to issuing the COPYBACK PROGRAM (85h-10h) command
to prevent the propagation of data errors.

One-Time Programmable (OTP) Operations
One-Time Programmable (OTP) Operations
This Micron NAND Flash device offers a protected, one-time programmable NAND
Flash memory area. Each target has a an OTP area with a range of OTP pages (see Table 15 (page 96)); the entire range is guaranteed to be good. Customers can use the
OTP area in any way they desire; typical uses include programming serial numbers or
other data for permanent storage.
The OTP area leaves the factory in an erased state (all bits are 1). Programming an OTP
page changes bits that are 1 to 0, but cannot change bits that are 0 to 1. The OTP area
cannot be erased, even if it is not protected. Protecting the OTP area prevents further
programming of the pages in the OTP area.
Enabling the OTP Operation Mode
The OTP area is accessible while the OTP operation mode is enabled. To enable OTP
operation mode, issue the SET FEATURES (EFh) command to feature address 90h and
write 01h to P1, followed by three cycles of 00h to P2 through P4.
ERASE commands are not valid while the target is in OTP operation mode.
Programming OTP Pages
Each page in the OTP area is programming using tthe PROGRAM OTP PAGE (80h-10h)
command. Each page can be programmed more than once, in sections, up to the maximum number allowed (see NOP in Table 15 (page 96)). The pages in the OTP area
must be programmed in ascending order.
If the host issues a PAGE PROGRAM (80h-10h) command to an address beyond the maximum page-address range, the target will be busy for tOBSY and the WP# status register
bit will be 0, meaning that the page is write-protected.
Protecting the OTP Area
To protect the OTP area, issue the OTP PROTECT (80h-10h) command to the OTP Protect Page. When the OTP area is protected it cannot be programmed further. It is not
possible to unprotect the OTP area after it has been protected.
Reading OTP Pages
To read pages in the OTP area, whether the OTP area is protected or not, issue the PAGE
READ (00h-30h) command.
If the host issues the PAGE READ (00h-30h) command to an address beyond the maximum page-address range, the data output will not be valid. To determine whether the
target is busy during an OTP operation, either monitor R/B# or use the READ STATUS
(70h) command. Use of the READ STATUS ENHANCED (78h) command is prohibited
while the OTP operation is in progress.
Returning to Normal Array Operation Mode
To exit OTP operation mode and return to normal array operation mode, issue the SET
FEATURES (EFh) command to feature address 90h and write 00h to P1 through P4.
If the RESET (FFh) command is issued while in OTP operation mode, the target will exit
OTP operation mode and enter normal operating mode. If the synchronous interface is
active, the target will exit OTP operation and enable the asynchronous interface.

range, and a block address of 0. Next, write the data to the cache register using data
input cycles. After data input is complete, issue the 10h command.
R/B# goes LOW for the duration of the array programming time, tPROG. The READ STATUS (70h) command is the only valid command for reading status in OTP operation
mode. The RDY bit of the status register will reflect the state of R/B#. Use of the READ
STATUS ENHANCED (78h) command is prohibited.
When the target is ready, read the FAIL bit of the status register to determine whether
the operation passed or failed (see Table 14 (page 65)).
The PROGRAM OTP PAGE (80h-10h) command also accepts the CHANGE WRITE COLUMN (85h) command during data input.
If a PROGRAM PAGE command is issued to the OTP area after the area has been protected, then R/B# goes LOW for tOBSY. After tOBSY, the status register is set to 60h.

Multi-Plane Operations
Multi-Plane Operations
Each NAND Flash logical unit (LUN) is divided into multiple physical planes. Each
plane contains a cache register and a data register independent of the other planes. The
planes are addressed via the low-order block address bits. Specific details are provided
in Device and Array Organization.
Multi-plane operations make better use of the NAND Flash arrays on these physical
planes by performing concurrent READ, PROGRAM, or ERASE operations on multiple
planes, significantly improving system performance. Multi-plane operations must be of
the same type across the planes; for example, it is not possible to perform a PROGRAM
operation on one plane with an ERASE operation on another.
Multi-Plane Addressing
Multi-plane commands require an address per operational plane. For a given multiplane operation, these addresses are subject to the following requirements:
• The LUN address bit(s) must be identical for all of the issued addresses.
• The plane select bit, BA[8], must be different for each issued address.
• The page address bits, PA[7:0], must be identical for each issued address.
The READ STATUS (70h) command should be used following MULTI-PLANE PROGRAM PAGE and ERASE BLOCK operations on a single die (LUN).

When issuing MULTI-PLANE PROGRAM or ERASE operations, use the READ STATUS
(70h) command and check whether the previous operation(s) failed. If the READ STATUS (70h) command indicates that an error occurred (FAIL = 1 and/or FAILC = 1), use
the READ STATUS ENHANCED (78h) command—time for each plane—to determine
which plane operation failed.

Interleaved Die (Multi-LUN) Operations
Interleaved Die (Multi-LUN) Operations
In devices that have more than one die (LUN) per target, it is possible to improve performance by interleaving operations between the die (LUNs). An interleaved die (multiLUN) operation is one that is issued to an idle die (LUN) (RDY = 1) while another die
(LUN) is busy (RDY = 0).
Interleaved die (multi-LUN) operations are prohibited following RESET (FFh, FCh), identification (90h, ECh, EDh), and configuration (EEh, EFh) operations until ARDY =1 for
all of the die (LUNs) on the target.
If a die (LUN) is performing a cache operation, like PROGRAM PAGE CACHE (80h-15h),
then the die (LUN) is able to accept the data for another cache operation when status
register bit 6 is 1. All operations, including cache operations, are complete on a die
when status register bit 5 is 1.
Use the READ STATUS ENHANCED (78h) command to monitor status for the addressed die (LUN). When multi-plane commands are used with interleaved die (multiLUN) operations, the multi-plane commands must also meet the requirements, see MultiPlane Operations for details. After the READ STATUS ENHANCED (78h) command has
been issued, the READ STATUS (70h) command may be issued for the previously addressed die (LUN).
See Command Definitions for the list of commands that can be issued while other die
(LUNs) are busy.
During an interleaved die (multi-LUN) operation that involves a PROGRAM-series
(80h-10h, 80h-15h, 80h-11h) operation and a READ operation, the PROGRAM-series operation must be issued before the READ-series operation. The data from the READseries operation must be output to the host before the next PROGRAM-series operation
is issued. This is because the 80h command clears the cache register contents of all
cache registers on all planes.

During an interleaved die (multi-LUN) operation, there are two methods to determine
operation completion. The R/B# signal indicates when all of the die (LUNs) have finished their operations. R/B# remains LOW while any die (LUN) is busy. When R/B# goes
HIGH, all of the die (LUNs) are idle and the operations are complete. Alternatively, the
READ STATUS ENHANCED (78h) command can report the status of each die (LUN) individually.

Error Management
Error Management
Each NAND Flash die (LUN) is specified to have a minimum number of valid blocks
(NVB) of the total available blocks. This means the die (LUNs) could have blocks that
are invalid when shipped from the factory. An invalid block is one that contains at least
one page that has more bad bits than can be corrected by the minimum required ECC.
Additional blocks can develop with use. However, the total number of available blocks
per die (LUN) will not fall below NVB during the endurance life of the product.
Although NAND Flash memory devices could contain bad blocks, they can be used
quite reliably in systems that provide bad-block management and error-correction algorithms. This type of software environment ensures data integrity.
NAND Flash devices are shipped from the factory erased. The factory identifies invalid
blocks before shipping by attempting to program the bad-block mark into every location in the first page of each invalid block. It may not be possible to program every
location with the bad-block mark. However, the first spare area location in each bad
block is guaranteed to contain the bad-block mark. This method is compliant with ONFI Factory Defect Mapping requirements. See the following table for the first spare area
location and the bad-block mark.
System software should check the first spare area location on the first page of each
block prior to performing any PROGRAM or ERASE operations on the NAND Flash device. A bad block table can then be created, enabling system software to map around
these areas. Factory testing is performed under worst-case conditions. Because invalid
blocks could be marginal, it may not be possible to recover this information if the block
is erased.
Over time, some memory locations may fail to program or erase properly. In order to
ensure that data is stored properly over the life of the NAND Flash device, the following
precautions are required:
• Always check status after a PROGRAM or ERASE operation
• Under typical conditions, use the minimum required ECC (see table below)
• Use bad-block management and wear-leveling algorithms
The first block (physical block address 00h) for each CE# is guaranteed to be valid
with ECC when shipped from the factory.

Because NAND Flash is designed for use in systems that are typically point-to-point connections, an option to control the drive strength of the output buffers is provided. Drive
strength should be selected based on the expected loading of the memory bus. There
are four supported settings for the output drivers: overdrive 2, overdrive 1, nominal,
and underdrive.
The nominal output drive strength setting is the power-on default value. The host can
select a different drive strength setting using the SET FEATURES (EFh) command.
The output impedance range from minimum to maximum covers process, voltage, and
temperature variations. Devices are not guaranteed to be at the nominal line.

Though all AC timing parameters are tested with a nominal input slew rate of 1 V/ns, it
is possible to run the device at a slower slew rate. The input slew rates shown below are
sampled, and not 100% tested. When using slew rates slower than the minimum values,
timing must be derated by the host.

1. Timing for tADL begins in the address cycle, on the final rising edge of WE# and ends
with the first rising edge of WE# for data input.
2. Data transition is measured ±200mV from steady-steady voltage with load. This parameter is sampled and not 100 percent tested.
3. AC characteristics may need to be relaxed if output drive strength is not set to at least
nominal.
4. Do not issue a new command during tWB, even if R/B# or RDY is ready.

Notes
1. Delay is from start of command to next command, address, or data cycle; start of address to next command, address, or data cycle; and end of data to start of next command, address, or data cycle.
2. This value is specified in the parameter page.
3. tCK(avg) is the average clock period over any consecutive 200-cycle window.
4. tCKH(abs) and tCKL(abs) include static offset and duty cycle jitter.
5. tDQSHZ begins when W/R# is latched HIGH by CLK. This parameter is not referenced to a
specific voltage level; it specifies when the device outputs are no longer driving.

Notes:
1. The pages in the OTP Block have an NOP of 4.
2. tITC (MAX) is the busy time when the interface changes from asynchronous to synchronous using the SET FEATURES (EFh) command or synchronous to asynchronous using the
RESET (FFh) command. During the tITC time, any command, including READ STATUS
(70h) and READ STATUS ENHANCED (78h), is prohibited.
3. tLPROG = tPROG (last page) + tPROG (last page - 1) - command load time (last page) address load time (last page) - data load time (last page).

Notes:
1. When CE# remains LOW, tCAD begins at the rising edge of the clock from which the last
data byte is input for the subsequent command or data input cycle(s).
2. tDSH (MIN) generally occurs during tDQSS (MIN).
3. tDSS (MIN) generally occurs during tDQSS (MAX).
4. The cycle that tCAD is measured from may be an idle cycle (as shown), another command cycle, an address cycle, or a data cycle. The idle cycle is shown in this diagram for
simplicity.
