Functional Description
2.1
Product Overview
The Numonyx™ StrataFlash® Cellular Memory (M18) device provides high read and
write performance at low voltage on a 16-bit data bus.
The flash memory device has a multi-partition architecture with read-while-program
and read-while-erase capability.
The device supports synchronous burst reads up to 108 MHz using ADV# and CLK
address-latching on some litho/density combinations and up to 133 MHz using CLK
address-latching only on some litho/density combinations. It is listed below in the
following table.

In continuous-burst mode, a data Read can traverse partition boundaries.
Upon initial power-up or return from reset, the device defaults to asynchronous arrayread mode. Synchronous burst-mode reads are enabled by programming the Read
Configuration Register. In synchronous burst mode, output data is synchronized with a
user-supplied clock signal. A WAIT signal provides easy CPU-to-flash memory
synchronization.
Designed for low-voltage applications, the device supports read operations with VCC at
1.8 V, and erase and program operations with VPP at 1.8 V or 9.0 V. VCC and VPP can
be tied together for a simple, ultra-low power design. In addition to voltage flexibility, a
dedicated VPP connection provides complete data protection when VPP is less than
VPPLK.
A Status Register provides status and error conditions of erase and program
operations.
One-Time-Programmable (OTP) registers allow unique flash device identification that
can be used to increase flash content security. Also, the individual block-lock feature
provides zero-latency block locking and unlocking to protect against unwanted program
or erase of the array.
The flash memory device offers three power savings features:
• Automatic Power Savings (APS) mode: The device automatically enters APS
following a read-cycle completion.
• Standby mode: Standby is initiated when the system deselects the device by
deasserting CE#.

Numonyx™ StrataFlash® Cellular Memory (M18)
• Deep Power-Down (DPD) mode: DPD provides the lowest power consumption and
is enabled by programming in the Enhanced Configuration Register. DPD is initiatied
by asserting the DPD pin.
2.2
Configuration and Memory Map
The Numonyx™ StrataFlash® Cellular Memory device features a symmetrical block
architecture. The flash device main array is divided as follows:
• The main array of the 128-Mbit device is divided into eight 16-Mbit partitions. Each
parition is divided into eight 256-KByte blocks: 8 x 8 = 64 blocks in the main array
of a 128-Mbit device.
• The main array of the 256-Mbit device is divided into eight 32-Mbit partitions. Each
parition is divided into sixteen 256-KByte blocks: 8 x 16 = 128 blocks in the main
array of a 256-Mbit device.
• The main array of the 512-Mbit device is divided into eight 64-Mbit partitions. Each
parition is divided into thirty-two 256-KByte blocks: 8 x 32 = 256 blocks in the
main array of a 256-Mbit device.
• The main array of the 1-Gbit device is divided into eight 128-Mbit partitions. Each
parition is divided into sixty-four 256-KByte blocks: 8 x 64 = 512 blocks in the
main array of a 1-Gbit device.
Each block is divided into as many as two-hundred-fifty-six 1-KByte programming
regions. Each region is divided into as many as thirty-two 32-Byte segments.

Electrical Characteristics
6.1
Initialization
Proper device initialization and operation is dependent on the power-up/down
sequence, reset procedure, and adequate power-supply decoupling. The following
sections describe each of these areas.
6.1.1
Power-Up/Down Characteristics
To prevent conditions that could result in spurious program or erase operations, the
power-up/power-down sequence shown in Table 12 is recommended. Note that each
power supply must reach its minimum voltage range before applying/removing the
next supply voltage.

* Power supplies connected or sequenced together.
Device inputs must not be driven until all supply voltages reach their minimum range.
RST# should be low during power transitions.
Note:
If VCCQ is below VLKOQ, the device is reset.
6.1.2
Reset Characteristics
During power-up and power-down, RST#should be asserted to prevent spurious
program or erase operations. While RST#is low, device operations are disabled; all
inputs such as address and control are ignored; and all outputs such as data and WAIT
are placed in High-Z. Invalid bus conditions are effectively masked out.
Upon power-up, RST#can be deasserted after tVCCPH, allowing the device to exit from
reset. Upon exiting from reset, the device defaults to asynchronous Read Array mode,
and the Status Register defaults to 0080h. Array data is available after tPHQV, or a buswrite cycle can begin after tPHWL.
If RST#is asserted during a program or erase operation, the operation will abort and
array contents at that location will be invalid.
For proper system initialization, connect RST#to the low-true reset signal that asserts
whenever the processor is reset. This will ensure the flash device is in the expected
read mode (i.e., Read Array) upon startup.
6.1.3
Power Supply Decoupling
High-speed flash memories require adequate power-supply decoupling to prevent
external transient noise from affecting device operations, and to prevent internallygenerated transient noise from affecting other devices in the system.
April 2008
309823-10
Datasheet
43
Numonyx™ StrataFlash® Cellular Memory (M18)
Ceramic chip capacitors of 0.01 to 0.1 µF capacitors should be used between all VCC,
VCCQ, VPPsupply connections and system ground. These high-frequency, inherently
low-inductance capacitors should be placed as close as possible to the device package,
or on the opposite side of the printed circuit board close to the center of the devicepackage footprint.
Larger (4.7 µF to 33.0 µF) electrolytic or tantulum bulk capacitors should also be
distributed as needed throughout the system to compensate for voltage sags caused by
circuit trace inductance.
Transient current magnitudes depend on the capacitive and inductive loading on the
device’s outputs. For best signal integrity and device performance, high-speed design
rules should be used when designing the printed-circuit board. Circuit-trace
impedances should match output-driver impedance with adequate ground-return
paths. This will help minimize signal reflections (overshoot/undershoot) and noise
caused by high-speed signal edge rates.

Read Timing Waveforms
The following sections show the timing waveforms for Asynchronous and Synchronous
read specifications for Non-Mux and AD-Mux M18 devices.
The Synchronous read timing waveforms apply to both the 108 and 133 MHz devices.
However please note that M18 devices which only support up to 108 MHz need not
meet the R313 to R317 timing specifications.

Please note that the WAIT signal polarity in all the timing waveforms is low-true
(RCR10 = 0). WAIT is shown as de-asserted with valid data (RCR8 = 0). WAIT is deasserted during asynchronous reads.

Write timing characteristics during erase suspend are the same as write-only operations.
A write operation can be terminated with either CE# or WE#.
Sampled, not 100% tested.
Write pulse width low (tWLWH or tELEH) is defined from CE# or WE# low (whichever occurs last) to CE# or WE# high
(whichever occurs first). Hence, tWLWH = tELEH = tWLEH = tELWH.
Write pulse width high (tWHWL or tEHEL) is defined from CE# or WE# high (whichever occurs first) to CE# or WE# low
(whichever occurs last). Hence, tWHWL = tEHEL = tWHEL = tEHWL).
tWHCH must be met when transitioning from a write cycle to a synchronous burst read. In addition there must be a CE#
toggle after WE# goes high.
VPP and WP# should be at a valid level until erase or program success is determined.
When doing a Read Status operation following any command that alters the Status Register data, W14 is 20ns.
Add 10ns if the write operations results in a RCR or block lock status change, for the subsequent read operation to reflect
this change.
This specification is applicable only if the part is configured in synchronous mode and an active clock is running. Either
tVHWL or tCHWL must be met depending on the whether the address is latched on ADV# or CLK.
These specifications are not applicable to 133 MHz devices.

please note that M18 devices which only support up to 108 MHz need not meet the
R313 to R317 timing specifications.
Please note that the WAIT signal polarity in all the timing waveforms is low-true
(RCR10 = 0). WAIT is de-asserted during asynchronous reads.

NOR Flash Bus Interface
The flash device uses low-true control signal inputs, and is selected by asserting the
chip enable (CE#) input. The output enable (OE#) input is asserted for read
operations, while the write enable (WE#) input is asserted for write operations. OE#
and WE# should never be asserted at the same time; otherwise, indeterminate device
operation will result. All bus cycles to or from the flash memory conform to standard
microcontroller bus cycles.
Commands are written to the device to control all operations.
Table 27 shows the logic levels that must be applied to the control-signal inputs of the
device for the various bus operations.

8.1
Bus Reads
To perform a read operation, both CE# and OE# must be asserted; #RST# and WE#
must be deasserted. OE# is the data-output control and when asserted, the output
data is driven on to the data I/O bus. All read operations are independent of the
voltage level on VPP.
The Automatic Power Savings (APS) feature provides low power operation following
reads during active mode. After data is read from the memory array and the address
lines are quiescent, APS automatically places the device into standby. In APS, device
current is reduced to ICCAPS.
The device supports two read configurations:
• Asynchronous reads. RCR15 = 1. This is the default configuration after power-up/
reset.
— Non-multiplexed devices support asynchronous page-mode reads. ADMultiplexed devices support only asychronous single-word reads.
• Synchronous Burst reads. RCR15 = 0.

Datasheet

Numonyx™ StrataFlash® Cellular Memory (M18)
8.1.1
Asynchronous single-word reads
In asynchronous single-word read mode, a single word of data corresponding to the
address is driven onto the data bus after the initial access delay. The address is latched
when ADV# is deasserted. For AD-multiplexed devices, ADV# must be deasserted
before OE# is asserted.
If only asynchronous reads are to be performed, CLK must be tied to a valid VIH or VIL
level, and the WAIT signal can be floated. In addition, for non-multiplexed devices,
ADV# must be tied to ground.
8.1.2
Asynchronous Page Mode (Non-multiplexed devices only)
In asynchronous page mode, sixteen data words are “sensed” simultaneously from the
flash memory array and loaded into an internal page buffer. The buffer word
corresponding to the initial address is driven onto the data bus after the initial access
delay. Subsequent words in the page are output after the page access delay. A[3:0]
bits determine which page word is output during a read operation. A[MAX:4] and ADV#
must be stable throughout the page access.
WAIT is deasserted during asynchronous page mode. ADV# can be driven high to latch
the address, or held low throughout the read cycle. CLK is not used for asynchronous
page-mode reads, and is ignored.
8.1.3
Synchronous Burst Mode
Synchronous burst mode is a clock-synchronous read operation that improves the read
performance of flash memory over that of asynchronous reads.
Synchronous burst mode is enabled by programming the Read Configuration Register
(RCR) of the flash memory device. The RCR is also used to configure the burst
parameters of the flash device, including Latency Count, burst length of 8, 16 and
continuous, and WAIT polarity.
Three additional signals are used for burst mode: CLK, ADV#, and WAIT.
The address for synchronous read operations is latched on the ADV# rising edge or the
first rising CLK edge after ADV# low, whichever occurs first for devices that support up
to 108 MHz. For devices that support up to 133 MHz, the address is latched on the last
CLK edge when ADV# is low.
During synchronous read modes, the first word is output from the data buffer on the
rising CLK edge after the initial access latency delay. Subsequent data is output on
rising CLK edges following a tCHQV delay. However, for a synchronous non-array read,
the same word of data will be output on successive rising clock edges until the burst
length requirements are satisfied.
8.1.3.1
WAIT Operation
Upon power up or exit from reset, WAIT polarity defaults to low-true operation (RCR10
= 0). During synchronous reads (RCR15 = 0), WAIT asserts when read data is invalid,
and deasserts when read data is valid. During asynchronous reads (RCR15 = 1), WAIT
is deasserted. During writes, WAIT is High-Z on non-mux devices, and deasserted on
AD-mux devices. Table 28 summarizes WAIT behavior.

8.2
Bus Writes
To perform a write operation, both CE# and WE# are asserted while RST# and OE# are
deasserted. All device write operations are asynchronous, with CLK being ignored, but
CLK can be kept active/toggling. During a write operation in non-muxed devices,
address and data are latched on the rising edge of WE# or CE#, whichever occurs first.
During a write operation in muxed devices, address is latched during the rising edge of
ADV# OR CE# whichever occurs first and Data is latched during the rising edge of WE#
OR CE# whichever occurs first.
8.3
Reset
The device enters a reset mode when RST# is asserted. In reset mode, internal
circuitry is turned off and outputs are placed in a high-impedance state. The device
shuts down any operation in progress, a process which takes a minimum amount of
time to complete.
To return from reset mode, RST# must be deasserted. Normal operation is restored
after a wake-up interval.
8.4
Deep Power-Down
The device enters DPD mode when the following two conditions are met: ECR15 is
set(1) and DPD is asserted. The two conditions can be satisfied in any order. ECR14 bit
determines the DPD asserted logic level. While in this mode, RST# and CE# must be
deasserted.
The device exits DPD mode when DPD is deasserted. There is an exit latency before the
device returns to standby mode and any operations are allowed. See the datasheet for
the timing specifications.
The device should not be placed in DPD mode when a program/erase operation is
ongoing or suspended. If the device enters DPD mode in the middle of a program,
erase or suspend, the operation is terminated and the memory contents at the aborted
location (for a program) or block (for an erase) are no longer valid.

Numonyx™ StrataFlash® Cellular Memory (M18)
While in DPD mode, the read-mode of each partition, configuration registers (RCR and
ECR), and block lock bits, are preserved. Status register is reset to 0080h; i.e., if the
Status register contains error bits, they will be cleared.
8.5
Standby
When CE# is deasserted, the device is deselected and placed in standby, substantially
reducing power consumption. In standby, data outputs are placed in high-Z,
independent of the level placed on OE#. If deselected during a Program or Erase
operation, the device continues to consume active power until the operation is
complete. There is no additional latency for subsequent read operations.
8.6
Output Disable
When OE# is deasserted with CE# asserted, the device outputs are disabled. Output
pins are placed in a high-impedance state. WAIT is deasserted in AD-muxed devices
and driven to High-Z in non-multiplexed devices.
8.7
Bus Cycle Interleaving
When issuing commands to the device, a read operation can occur between the two
write cycles of a 2-cycle command. (See Figure 43 and Figure 44) However, a write
operation cannot occur between the two write cycles of a 2-cycle command and will
cause a command sequence error (See Figure 45).

Read Operation During Program Buffer fill
Due to the large buffer size of devices, the system interrupt latency may be impacted
during the buffer fill phase of a buffered programming operation. Please refer to the
relevant Application Note listed in Section 1.4, “Additional Information” on page 7 to
implement a software solution for your system.
8.8
Read-to-Write and Write-to-Read Bus Transitions
Consecutive read and write bus cycles must be properly separated from each other to
avoid bus contention. These cycle separation specs are described in the sections below.
8.8.1
Write to Asynchronous read transition
To transition from a bus write to an asynchronous read operation, either CE# or ADV#
must be toggled after WE# goes high.
8.8.2
Write to synchronous read transition
To transition from a bus write to a synchronous read operation, either CE# or ADV#
must be toggled after WE# goes high. In addition, W19 (tWHCH -WE# high to CLK high)
must be met.
8.8.3
Asynchronous/Synchronous read to write transition
To transition from a asynchronous/synchronous read to a write operation, either CE# or
ADV# must be toggled after OE# goes high.
8.8.4
Bus write with active clock
To perform a bus write when the device is in synchronous mode and the clock is active,
W21 (tVHWL- ADV# High to WE# Low) or W22 (tCHWL -Clock high to WE# low) must be
met.

NOR Flash Operations
This section describes the operational features of NOR flash memory. Operations are
command-based—command codes are first issued to the device, and then the device
performs the desired operation. All command codes are issued to the device using buswrite cycles as explained in Section 3.0, “NOR Flash Bus Interface” on page 10. A
complete list of available command codes can be found in Section 5.0, “Device
Command Codes” on page 40.
9.1
Status Register
The Status Register (SR) is a 16-bit, read-only register that indicates device and
partition status, and operational errors. To read the Status Register, issue the Read
Status Register command. Subsequent reads output Status Register information on
AD/DQ[15:10].
SR status bits are set and cleared by the device. SR error bits are set by the device,
and must be cleared using the Clear Status Register command. Upon power-up or exit
from reset, the Status Register defaults to 0080h.

Clearing the Status Register
The Status Register (SR) contain status and error bits which are set by the device. SR
status bits are cleared by the device; however, SR error bits are cleared by issuing the
Clear Status Register command. Resetting the device also clears the Status Register.

Depending on the current state of the partition, issuing the Clear Status Command will
place the addressed partition in Read Status mode. Please see 'Next State' Table for
further details. Other partitions are not affected.
Note:
Care should be taken to avoid Status Register ambiguity. If a command sequence error
occurs while in an Erase Suspend condition, the Status Register will indicate a
Command Sequence error by setting SR4 and SR5. When the erase operation is
resumed (and finishes), any errors that may have occurred during the erase operation
will be masked by the Command Sequence error. To avoid this situation, clear the
Status Register prior to resuming a suspended erase operation.
The Clear Status Register command functions independent of the voltage level on VPP.

Read Configuration Register
The Read Configuration Register (RCR) is a 16-bit read/write register used to select
bus-read modes, and to configure synchronous-burst read characteristics of the flash
device. All Read Configuration Register bits are set and cleared using the Program Read
Configuration Register command.
April 2008
309823-10
Datasheet

Numonyx™ StrataFlash® Cellular Memory (M18)
Upon power-up or exit from reset, the Read Configuration Register defaults to
asynchronous mode (RCR15 = 1; RCR[14:11] and RCR[9:0] are ignored).
To read the RCR value, issue the Read Device Information command to the desired
partition. Subsequent reads from the <partition base address> + 05h will output
RCR[15:0] on the data bus.
When using a Latency Count of Code 2 and a Data Hold of two cycles (CR9 = 1), WAIT
must be configured to deassert with valid data (CR8 = 0).

Enhanced Configuration Register
The Enhanced Configuration Register (ECR) is a volatile 16-bit, read/write register used
to select Deep Power Down (DPD) operation and to modify the output-driver strength
of the flash device. All Enhanced Configuration Register bits are set and cleared using
the Program Enhanced Configuration Register command. Upon power-up or exit from
reset, the Enhanced Configuration Register defaults to 0004h.
To read the value of the ECR, issue the Read Device Information command to the
desired partition. Subsequent reads from the <partition base address> + 06h returns
ECR[15:0].

Programming the ECR
The ECR is programmed by issuing the Program Enhanced Configuration Register
command. This is a two-cycle command sequence requiring a Setup command to be
issued first, followed by a Confirm command. Bus-write cycles to the flash device
between the setup and confirm commands are not allowed—a command sequence
error will result. However, flash bus-read cycles between the Setup and Confirm
commands are allowed.

To program the Enhanced Configuration Register, the desired settings for ECR[15:0]
are placed on the address bus. The setup command (0060h) is driven on the data bus.
Upon issuing the setup command, the device/addressed partition is automatically
changed to Read Status Register mode.
Next, the Confirm command (0004h) is driven on the data bus. After issuing the
Confirm command, the addressed partition is automatically switched to Read Array
mode.
This command functions independently of the applied VPP voltage.
Note:
Since the desired register value is placed on the address lines, any hardwareconnection offsets between the host’s address outputs and the flash device’s address
inputs must be considered, similar to programming the RCR.
9.4
Read Operations
The following types of data can be read from the device: array data, device
information, CFI data, and device status Upon power-up or return from reset, the
device defaults to Read Array mode. To change the device’s read mode, the appropriate
command must be issued to the device. Table 36, “Read Mode Command Bus Cycles”
shows the command codes used to configure the device for the desired read mode. The
following sections describe each read mode.

Read Array
Upon power-up or exit from reset, the device defaults to Read Array mode. Issuing the
Read Array command places the addressed partition in Read Array mode. Subsequent
reads output array data. The addressed partition remains in Read Array mode until a
different read command is issued, or a program or erase operation is performed in that
partition, in which case, the read mode is automatically changed to Read Status.
To changea partition to Read Array mode while it is programming or erasing, first issue
the Suspend command. After the operation has been suspended, issue the Read Array
command to the partition. When the program or erase operation is subsequently
resumed, the read state of the partition will not change. To change the read state of
the partition to Status read mode, issue a Read Status command to the partition.

Numonyx™ StrataFlash® Cellular Memory (M18)
Note:
Issuing the Read Array command to a partition that is actively programming or erasing
causes subsequent reads from that partition to output invalid data. Valid array data is
output only after the program or erase operation has finished.
The Read Array command functions independent of the voltage level on VPP.
9.4.2
Read Status Register
Issuing the Read Status Register command places the addressed partition in Read
Status Register mode. Subsequent reads from that partition output Status Register
information. The addressed partition remains in Read Status Register mode until a
different read-mode command is issued to that partition. Performing a program, erase,
or block-lock operation also changes the partition’s read mode to Read Status Register
mode.
The Status Register is updated on the falling edge of CE#, or OE# when CE# is low.
Status Register contents are valid only when SR7 = 1.
The Read Status Register command functions independent of the voltage level on VPP.
9.4.3
Read Device Information
Issuing the Read Device Information command places the addressed partition in Read
Device Information mode. Subsequent reads output device information on the data
bus. The address offsets for reading the available device information are shown here.

CFI Query
Issuing the CFI Query command places the addressed partition in CFI Query mode.
Subsequent reads from that partition output CFI information.
The addressed partition remains in CFI Query mode until a different read command is
issued, or a program or erase operation is performed, which changes the read mode to
Read Status Register mode.
Note:
Issuing the CFI Query command to a partition that is actively programming or erasing
changes that partition’s read mode to CFI Query mode. Subsequent reads from that
partition will return invalid data until the program or erase operation has completed.
The CFI Query command functions independent of the voltage level on VPP.
9.5
Programming Modes
To understand programming modes, it is also important to understand the fundamental
memory array configuration. The flash device main array is divided as follows:
• The main array of the 128-Mbit device is divided into eight 16-Mbit partitions. Each
parition is divided into eight 256-KByte blocks: 8 x 8 = 64 blocks in the main array
of a 128-Mbit device.
• The main array of the 256-Mbit device is divided into eight 32-Mbit partitions. Each
partition is divided into sixteen 256-KByte blocks: 8 x 16 = 128 blocks in the main
array of a 256-Mbit device.
• The main array of the 512-Mbit device is divided into eight 64-Mbit partitions. Each
partition is divided into thirty-two 256-KByte blocks: 8 x 32 = 256 blocks in the
main array of a 256-Mbit device.
• The main array of the 1-Gbit device is divided into eight 128-Mbit partitions. Each
partition is divided into sixty-four 256-KByte blocks: 8 x 64 = 512 blocks in the
main array of a 1-Gbit device.
Each block is divided into as many as two-hundred-fifty-six 1-KByte programming
regions. Each region is divided into as many as thirty-two 32-Byte segments.
Each programming region in a flash block can be configured for one of two
programming modes: Control Mode or Object Mode. The programming mode is
automatically set based on the data pattern when a region is first programmed. The
selection of either Control Mode or Object Mode is done according to the specific needs
of the system with consideration given to two types of information:
• Control Mode: Flash File System (FFS) or Header information, including frequently
changing code or data
• Object Mode: Large, infrequently changing code or data, such as objects or
payloads
By implementing the appropriate programming mode, software can efficiently organize
how information is stored in the flash memory array.
Control Mode programming regions and Object Mode programming regions can be
intermingled within the same erase block. However, the programming mode of any
region within a block can be changed only after erasing the entire block.

83
Numonyx™ StrataFlash® Cellular Memory (M18)
9.5.1
Control Mode
Control Mode programming is invoked when only the A-half (A3 = 0) of the
programming region is programmed to 0s, as shown in Figure 47, “Configurable
Programming Regions: Control Mode and Object Mode” on page 85. The B-half (A3 =
1) remains erased. Control mode allows up to 512 bytes of data to be programmed in
the region. The information can be programmed in bits, bytes, or words.
Control Mode supports the following programming methods:
— Single-word Programming (0041h)
— Buffered Programming (00E9h/00D0h), and
— Buffered Enhanced Factory Programming (0080h/00D0h)
When buffered programming is used in Control Mode, all addresses must be in the Ahalf of the buffer (A3 = 0). During buffer fill, the B-half (A3 = 1) addresses do not need
to be filled with 0xFFFF.
Control Mode programming is useful for storing dynamic information, such as FFS
Headers, File Info, and so on. Typically, Control Mode programming does not require
the entire 512 bytes of data to be programmed at once. It may also contain data that is
changed after initial programming using a technique known as “bit twiddling”. Header
information can be augmented later with additional new information within a Control
Mode-programmed region. This allows implementation of legacy file systems, as well as
transaction-based power-loss recovery.
In a control mode region, programming operations can be performed multiple times.
However, care must be taken to avoid programming any zero’s in the B-half (A3 = 1) of
the region. Violation of this usage will cause SR4 and SR9 to be set, and the program
operation will be aborted. See Table 38, “Programming Region Next State Table” on
page 88 for details.

Object Mode
Object mode programming is invoked when one or more bits are programmed to zero
in the B-half of the programming region (A3 = 1). Object mode allows up to 1KB to be
stored in a programming region. Multiple regions are used to store more than 1Kbyte of
information. If the object is less than 1Kbyte, the unused content will remain as 0xFFFF
(erased).
Object Mode supports two programming methods:
— Buffered Programming (00E9h/00D0h), and
— Buffered Enhanced Factory Programming (0080h/00D0h)
April 2008

Datasheet
85
Numonyx™ StrataFlash® Cellular Memory (M18)
Single-word programming (0041h) is not supported in Object mode. To perform
multiple programming operations within a programming region, Control mode must be
used.
Object mode is useful for storing static information, such as objects or payloads, that
rarely change.
Once the programming region is configured in Object mode, it cannot be augmented or
over-written without first erasing the entire block containing the region. Subsequent
programming operations to a programming region configured in Object mode will cause
SR4 and SR8 to be set and the program operation to be aborted. See Table 38,
“Programming Region Next State Table” on page 88 for details.
Note:
Datasheet
86
Issuing the 41h command to the B-half of an erased region will set error bits SR8 and
SR9, and the programming operation will not proceed. See Table 38, “Programming
Region Next State Table” on page 88 for more details.

Programming Operations
Programming the flash array changes ‘ones’ to ‘zeros’. To change zeros to ones, an
Erase operation must be performed. Only one programming operation can occur at a
time. Programming is permitted during Erase Suspend.
Information is programmed into the flash array by issuing the appropriate command.

Caution:
All programming operations require the addressed block to be unlocked, and a
valid VPP voltage applied throughout the programming operation. Otherwise,
the programming operation will abort, setting the appropriate Status Register
error bit(s).
The following sections describe each programming method.
9.6.1
Single-Word Programming
Main array programming is performed by first issuing the Single-Word Program
command. This is followed by writing the desired data at the desired array address. The
read mode of the addressed partition is automatically changed to Read Status Register
mode, which remains in effect until another read-mode command is issued.
Datasheet
88
April 2008
309823-10
Numonyx™ StrataFlash® Cellular Memory (M18)
Note:
Issuing the Read Status Register command to another partition switches that partition’s
read mode to Read Status Register mode, thereby allowing programming progress to
be monitored from that partition’s address.
Single-Word Programming is supported in Control mode only. The array address
specified must be in the A-half of the programming region.
During programming, the Status Register indicates a busy status (SR7 = 0). Upon
completion, the Status Register indicates a ready status (SR7 = 1). The Status Register
should be checked for any errors, then cleared.
The only valid commands during programming are Read Array, Read Device
Information, CFI Query, Read Status and Program Suspend. After programming has
finished, any valid command can be issued.
Note:
Issuing the Read Array, Read Device Information, or CFI Query command to a partition
that is actively programming causes subsequent reads from that partition to output
invalid data. Valid data is output only after the program operation has finished.
Standby power levels are not realized until the programming operation has finished.
Asserting RST# immediately aborts the programming operation, and array contents at
the addressed location are indeterminate. The addressed block should be erased, and
the data re-programmed.
9.6.2
Buffered Programming
Buffered Programming programs multiple words simultaneously into the flash memory
array. Data is first written to a write buffer and then programmed into the flash
memory array in buffer-size increments. This can significantly reduce the effective
word-write time. Section 6.0, “Flow Charts” on page 41 contains a flow chart of the
buffered-programming operation.
Note:
Optimal performance and power consumption is realized only by aligning the start
address on 32-word boundaries, e.g., A[4:0] = 00000b. Crossing a 32-word boundary
during a Buffered Programming operation can cause the programming time to double.
Buffered Programming is supported in both Control mode and Object mode. In Object
mode, the region must be programmed only once between erases. However in Control
mode, the region may be programmed multiple times.
Caution:
When using the Buffered Program command in Object mode, the start address
must be aligned to the 512-word buffer boundary. In Control mode, the
programming array address specified must be in the A-half of the
programming region.
First issue the Read Status command to the desired partition. The read mode of the
addressed partition is changed to Read Status Register mode.
Poll SR7 to determine write-buffer availability (0 = not available, 1 = available). If the
write buffer is not available, re-issue the Read Status command and check SR7; repeat
until SR7 = 1.
If desired issue a Read Array command to the desired partition to change the read
mode of the partition to Array reads.
To perform a buffered programming operation, issue the Buffered Program setup
command at the desired starting address. Next, issue a word count at the desired
starting address. The word count is the total number of words to be written into the
write buffer, minus one. This value can range from 0000h (one word) up to a maximum
of 01FFh (512 words). Exceeding the allowable range causes the operation to abort.

Numonyx™ StrataFlash® Cellular Memory (M18)
Following the word count, subsequent bus-write cycles fill the write buffer with userdata up to the word count.
Note:
User-data is programmed into the flash array at the address issued when filling the
write buffer.
The Confirm command (00D0h) is issued after all user-data is written into the write
buffer. The read mode of the device/addressed partition is automatically changed to
Read Status Register mode. If other than the Confirm command is issued to the device,
a command sequence error occurs and the operation aborts.
After the Confirm command has been issued, the write-buffer contents are
programmed into the flash memory array. The Status Register indicates a busy status
(SR7 = 0) during array programming.
During array programming, the only valid commands are Read Array, Read Device
Information, CFI Query, Read Status, and Program Suspend. After array programming
has completed (SR7 = 1), any valid command can be issued. Reading from another
partition is allowed while data is being programmed into the flash memory array from
the write buffer.
Note:
Issuing the Read Array, Read Device Information, or CFI Query command to a partition
that is actively programming or erasing causes subsequent reads from that partition to
output invalid data. Valid data is output only after the program or erase operation has
finished.
Upon completion of array programming, the Status Register indicates ready (SR7 =
1b). A full Status Register check should be performed to check for any programming
errors. Then the Status Register should be cleared using the Clear Status Register
command.
A subsequent buffered programming operation can be initiated by repeating the
buffered programming sequence. Any errors in the Status Register caused by the
previous operation must be cleared to prevent them from masking any errors that may
occur during the subsequent operation.
9.6.3
Buffered Enhanced Factory Programming (BEFP)
Buffered Enhanced Factory Programming (BEFP) improves programming performance
through the use of the write buffer, elevated programming voltage (VPPH), and
enhanced programming algorithm. User-data is written into the write buffer, then the
buffer contents are automatically written into the flash array in buffer-size increments.
BEFP is allowed in both Control Mode and Object Mode. The programming mode
selection for the entire flash array block is driven by the specific type of information,
such as header or object data. Header/object data is aligned on a 1 KB programming
region boundary in the main array block.
Internal verification during programming (inherent to MLC technology) and Status
Register error checking are used to determine proper completion of the programming
operation. This eliminates delays incurred when switching between single-word
program and verify operations.
BEFP consists of three distinct phases:
1. Setup Phase: VPPH and block-lock checks
2. Program/Verify Phase: buffered programming and verification
3. Exit Phase: block-error check

Section 6.0, “Flow Charts” on page 41 contains a flow chart of the BEFP operation.
Table 40, “BEFP Requirements and Considerations” on page 91 lists specific BEFP
requirements and considerations.
Note:
For BEFP voltage and temperature operating restrictions, see the datasheet. The block
erase cycles in Table 40, “BEFP Requirements and Considerations” are recommended
for optimal performance. If exceeded some degradation in performance may occur;
however, the internal algorithm will still function correctly.

BEFP programs within one block at a time
BEFP cannot be suspended
9.6.3.1
Setup Phase
Issuing the BEFP Setup and Confirm command sequence starts the BEFP algorithm. The
read mode of the addressed partition is automatically changed to Read Status Register
mode.
The address used when issuing the setup/confirm commands must be buffer-size
aligned within the block being programmed -- buffer contents cannot cross block
boundaries.
Caution:
The Read Status Register command must not be issued -- it will be interpreted
as data to be written to the write buffer.
A setup delay (tBEFP/Setup) occurs while the internal algorithm checks VPP and block-lock
status. If errors are detected, the appropriate Status Register error bits are set and the
operation aborts.
The Status Register should be polled for successful BEFP setup, indicated by SR[7,0] =
0 (Device Busy, Buffer Ready for Data).
9.6.3.2
Program/Verify Phase
Data is first written into the write buffer, then programmed into the flash array. During
the buffer-fill sequence, the address used must be buffer-size aligned. Use of any other
address will cause the operation to abort with a program fail error, and any data
previously loaded in the buffer will not be programmed into the array.
The buffer-fill data is stored in sequential buffer locations starting at address 00h. A
word count equal to the maximum buffer size is used, therefore, the buffer must be
completely filled. If the amount of data is less than the maximum buffer size, the
remaining buffer locations must be “padded” with FFFFh to completely fill the buffer.
Flash array programming starts as soon as the write buffer is full. Data words from the
write buffer are programmed into sequential array locations. SR0 = 1 indicates the
write buffer is not available while the BEFP algorithm programs the array.
April 2008
309823-10
Datasheet
91
Numonyx™ StrataFlash® Cellular Memory (M18)
The Status Register should be polled for SR0 = 0 (Buffer Ready for Data) to determine
when the array programming has completed, and the write buffer is again available for
loading. The internal address is automatically incremented to enable subsequent array
programming to continue from where the previous buffer-fill/array-program sequence
ended within the block. This cycle can be repeated to program the entire block.
To exit the Program/Verify Phase, write FFFFh to an address outside of the block.
9.6.3.3
Exit Phase
The Status Register should be polled for SR7 = 1 (Device Ready) indicating the BEFP
algorithm has finished running, and the device has returned to normal operation. A full
error check should be performed to ensure the block was programmed successfully.
9.7
Block Erase Operations
Erasing a block changes ‘zeros’ to ‘ones’. To change ones to zeros, a program operation
must be performed (see Section 9.6, “Programming Operations). Erasing is performed
on a block basis— an entire block is erased each time an erase command sequence is
issued. Once a block is fully erased, all addressable locations within that block read as
logical ‘ones’ (FFFFh).
Only one block-erase operation can occur at a time. A block-erase operation is not
permitted during Program Suspend.
To perform a block-erase operation, issue the Block Erase command sequence at the
desired block address. Table 41 shows the two-cycle Block Erase command sequence.

Setup Write Cycle
Address Bus
Block Erase
Caution:

Data Bus
00D0h
All block-erase operations require the addressed block to be unlocked, and a
valid voltage applied to VPP throughout the block-erase operation. Otherwise,
the operation aborts, setting the appropriate Status Register error bit(s).
The Erase Confirm command latches the address of the block to be erased. The
addressed block is preconditioned (programmed to all zeros), erased, and then verified.
The read mode of the addressed partition is automatically changed to Read Status
Register mode, and remains in effect until another read-mode command is issued.
Note:
Issuing the Read Status Register command to another partition switches that partition’s
read mode to the Read Status Register, thereby allowing block-erase progress to be
monitored from that partition’s address. SR0 indicates whether the addressed partition
or other partition is erasing.
During a block-erase operation, the Status Register indicates a busy status (SR7 = 0).
Upon completion, the Status Register indicates a ready status (SR7 = 1). The Status
Register should be checked for any errors, and then cleared.
The only valid commands during a block erase operation are Read Array, Read Device
Information, CFI Query, Read Status and Erase Suspend. After the block-erase
operation has completed, any valid command can be issued.

Note:
Issuing the Read Array command to a partition that is actively erasing a main block
causes subsequent reads from that partition to output invalid data. Valid array data is
output only after the block-erase operation has finished.
Standby power levels are not realized until the block-erase operation has finished.
Asserting RST# immediately aborts the block-erase operation, and array contents at
the addressed location are indeterminate. The addressed block should be erased, and
the data re-programmed.
9.8
Blank Check Operation
Blank Check is used to see if a main-array block is completely erased. A Blank Check
operation is performed one block at a time, and cannot be used during Program
Suspend or Erase Suspend.
To use Blank Check, first issue the Blank Check setup command followed by the confirm
command. The read mode of the addressed partition is automatically changed to Read
Status Register mode, which remains in effect until another read-mode command is
issued.

During a blank check operation, the Status Register indicates a busy status (SR7 = 0).
Upon completion, the Status Register indicates a ready status (SR7 = 1).
Note:
Issuing the Read Status Register command to another partition switches that partition’s
read mode to Read Status Register mode, thereby allowing the blank check operation
to be monitored from that partition’s address.
The Status Register should be checked for any errors, and then cleared. If the Blank
Check operation fails, i.e., the block is not completely erased, then the Status Register
will indicate a Blank Check error (SR[7,5] = 1).
The only valid command during a Blank Check operation is Read Status. Blank Check
cannot be suspended. After the blank check operation has completed, any valid
command can be issued.
9.9
Suspend and Resume
Program and erase operations of the main array can be suspended to perform other
device operations, and then subsequently resumed. However, OTP Register
programming or blank check operations cannot be suspended.
To suspend an on-going erase or program operation, issue the Suspend command to
any device address; the corresponding partition is not affected. Table 43 shows the
Suspend and Resume command bus-cycles.
Note:
April 2008
309823-10
Issuing the Suspend command does not change the read mode of the partition. The
partition will be in Read Status Register mode from when the erase or program
command was first issued, unless the read mode was changed prior to issuing the
Suspend command.

The program or erase operation suspends at pre-determined points during the
operation after a delay of tSUSP. Suspend is achieved when SR[7,6] = 1 (erasesuspend) or SR[7,2] = 1 (program-suspend).
Note:
Throughout the Block Erase Suspend or Program Suspend period, the addressed block
must remain unlocked and a valid voltage applied to VPP. Otherwise, the erase or
program operation will abort, setting the appropriate Status Register error bit(s). Also,
WP# must remain unchanged.
Asserting RST# aborts suspended block-erase and programming operations -- array
contents at the addressed locations are indeterminate. The addressed block should be
erased, and the data re-programmed.
Not all commands are allowed when the device is suspended. Table 44 shows which
device commands are allowed during Program Suspend or Erase Suspend.

During Suspend, reading from a block that is being erased or programmed is not
allowed. Also, programming to a block that is in erase-suspend state is not allowed,
and if attempted, will result in Status Register program error to be set (SR4 = 1).
A block-erase under program-suspend is not allowed. However, word-program under
erase-suspend is allowed, and can be suspended. This results in a simultaneous erasesuspend/ program-suspend condition, indicated by SR[7,6,2] = 1.
To resume a suspended program or erase operation, issue the Resume command to
any device address. The read mode of the resumed partition is unchanged; issue the
Read Status Register command to return the partition to Read Status mode. The
operation continues where it left off, and the respective Status Register suspend bits
are cleared.

When the Resume command is issued during a simultaneous erase-suspend/ programsuspend condition, the programming operation is resumed first. Upon completion of the
programming operation, the Status Register should be checked for any errors, and

Upon completion of the erase operation, the Status Register should be checked for any
errors, and cleared.

Simultaneous Operations
The multi-partition architecture of the flash device allows programming or erasing to
occur in one partition while reads are performed from another partition. Only status
reads are allowed in partitions that are busy programming or erasing.
Note:
When OTP Registercommands are issued to a parameter any partition address, the OTP
Registeris mapped onto that partition.
Table 45, “Read-While-Program and Read-While-Erase Rules” shows the rules for
reading from a partition while simultaneously programming or erasing within another

Security
The flash device incorporates features for protecting main-array contents and for
implementing system-level security schemes. The following sections describe the
available features.
9.11.1
Block Locking
Two methods of block-lock control are available: software and hardware. Software
control uses the Block Lock and Block Unlock commands; hardware control uses WP#
along with the Block Lock-Down command.
Upon power up or exit from reset, all main array blocks are locked, but not locked
down. Locked blocks cannot be erased or programmed.
Block lock and unlock operations are independent of the voltage level on VPP.
Table 46 summarizes the command bus-cycles.

To lock, unlock, or lock-down a block, first issue the setup command to any address
within the desired block. The read mode of the addressed partition is automatically
changed to Read Status Register mode. Next, issue the desired confirm command to
the block’s address. Note that the confirm command determines the operation
performed. The Status Register should be checked for any errors, and then cleared.
The lock status of a block can be determined by issuing the Read Device Information
command, and then reading from <block base address> + 02h. DQ0 indicates the lock
status of the addressed block (0 = unlocked, 1 = locked), and DQ1 indicates the lockdown status of the addressed block (0 = lock-down not issued; 1 = locked-down
issued). Section 9.4.3, “Read Device Information” on page 82 summarizes the details
of this operation.
Blocks cannot be locked or unlocked while being actively programmed or erased. Blocks
can be locked or unlocked during erase-suspend, but not during program-suspend.
Note:
If a block-erase operation is suspended, and then the block is locked or locked down,
the lock status of the block will be changed immediately. When resumed, the erase
operation will still complete.
Block lock-down protection is dependent on WP#. When WP# = VIL , blocks locked
down are locked, and cannot be unlocked using the Block Unlock command. When
WP# = VIH, block lock-down protection is disabled—locked-down blocks can be
individually unlocked using the Block Unlock command. Subsequently, when WP# =
VIL, previously locked-down blocks are once again locked and locked-down, including
locked-down blocks that may have been unlocked while WP# was de-asserted.
A locked-down block can only be unlocked by issuing the Unlock Block command with
WP# deasserted. To return an unlocked block to the locked-down state, a Lock-Down
command must be issued prior to asserting WP#.
Issuing the Block Lock-Down command to an unlocked block does not lock the block.
However, asserting WP# after issuing the Block Lock-Down command locks (and locks
down) the block. Lock-down for all blocks is cleared upon power-up or exit from reset.
Figure 49 summarizes block-locking operations.

One-Time Programmable (OTP) Registers
The device contains seventeen 128-bit One-Time Programmable (OTP) Registers, and
twoa 16-bit OTP Lock Registers, as shown in Figure 50, “2-Kbit OTP Registers” on
page 98. The OTP Lock Register 0 is used for locking the OTP Register 0, and OTP Lock
Register 1 is used for locking OTP Registers 1 through 16.
The OTP Register 0 consists of two 64-bit segments: a lower segment that is preprogrammed with a unique 64-bit value and locked at the factory; and an upper
segment that contains all “ones” and is user-programmable. OTP Registers 1 through
16 contain all “ones” and are user-programmable.

OTP Lock Register 0
Each register contains OTP bits that can only be programmed from “one” to “zero” register bits cannot be erased from “zero” back to “one”. This feature makes the OTP
registers particularly useful for implementing system-level security schemes, for
permanently storing data, or for storing fixed system parameters.
OTP Lock Register bits “lock out” subsequent programming of the corresponding OTP
register. Each OTP Register can be locked by programming its corresponding lock bit to
zero. As long as an OTP register remains unlocked (that is, its lock bit = 1), any of its
remaining “one” bits can be programmed to “zero”.
Caution:
Once an OTP Register is locked, it cannot be unlocked. Attempts to program a
locked OTP Register will fail with error bits set.
To program any OTP bits, first issue the Program OTP Register setup command at any
device address. Next, write the desired OTP Register data at the desired OTP Register
address. OTP Register and OTP Lock Register programming is performed 16 bits at a
time; only “zeros” within the data word affect any change to the OTP register bits.

To read from any of the OTP registers, first issue the Read Device Information
command. Then read from the desired OTP Register address offset. For additional
details, refer to Section 9.4.3, “Read Device Information” on page 82.
9.11.3
Global Main-Array Protection
Global main-array protection can be implemented by controlling VPP. When
programming or erasing main-array blocks, VPP must be equal to, or greater than VPPL
(min). When VPP is below VPPLK, program or erase operations are inhibited, thus
providing absolute protection of the main array.
Various methods exist for controlling VPP, ranging from simple logic control to off-board
voltage control. Figure 51 shows example VPP supply connections that can be used to
support program/erase operations and main-array protection.

NOTES:
1. The device outputs the Status Register when read.
2. The device outputs the array data when read.
3. Buffer Programming is available in the main array only. This
algorithm may be used for MLC or PSBC programming. Upon
issuing 0xE9 the partition state does not changed.
4. Word count value on D[8:0] is loaded into the word count
register. Count ranges for this device are N = 0x000 to 0x1FF.
5. Buffer address on A[MAX:9] specifies a single 512-word
buffer-size array region. This is latched and held constant
during the entire operation.
6. The word address within the buffer, specified by A [8:0], is
provided. Upper address bits are ignored.
7. The device aborts the Buffer Program command if the current
address is outside the original block address .
8. Upon issuing 0xD0 the partition is placed in Status Read
mode. If block address changes, Buffer Program will abort.
9. The Status Register indicates an improper command
sequence if the Buffer Program command is aborted; use the
Clear Status Register command to clear error bits.

Common Flash Interface
The Common Flash Interface (CFI) is part of an overall specification for multiple
command-set and control-interface descriptions. It describes the database structure
containing the data returned by a read operation after issuing the CFI Query command.
System software can parse this database structure to obtain information about the
flash device, such as block size, density, bus width, and electrical specifications. The
system software will then know which command set(s) to use to properly perform flash
writes, block erases, reads and otherwise control the flash device.
12.1
Query Structure Output
The Query database allows system software to obtain information for controlling the
flash device. This section describes the device’s CFI-compliant interface that allows
access to Query data.
Query data are presented on the lowest-order data outputs (A/DQ7-0) only. The
numerical offset value is the address relative to the maximum bus width supported by
the device. On this family of devices, the Query table device starting address is a 10h,
which is a word address for x16 devices.
For a word-wide (x16) device, the first two Query-structure bytes, ASCII “Q” and “R,”
appear on the low byte at word addresses 10h and 11h. This CFI-compliant device
outputs 00h data on upper bytes. The device outputs ASCII “Q” in the low byte
(A/DQ7-0) and 00h in the high byte (A/DQ15-8).
At Query addresses containing two or more bytes of information, the least significant
data byte is presented at the lower address, and the most significant data byte is
presented at the higher address.
In all of the following tables, addresses and data are represented in hexadecimal
notation, so the “h” suffix has been dropped. In addition, since the upper byte of wordwide devices is always “00h,” the leading “00” has been dropped from the table
notation and only the lower byte value is shown. Any x16 device outputs can be
assumed to have 00h on the upper byte in this mode.

Block Status Register
The Block Status Register indicates whether an erase operation completed successfully
or whether a given block is locked or can be accessed for flash program/erase
operations.
Block Erase Status (BSR[1]) allows system software to determine the success of the
last block erase operation. BSR[1] can be used just after power-up to verify that the
VCC supply was not accidentally removed during an erase operation. Only issuing
another operation to the block resets this bit. The Block Status Register is accessed
from word address 02h within each block.

Notes:
1.
The Partition Data When Read field shows what users read from the flash chip after issuing the appropriate command,
given the Partition Address is not changed from the address given during the command. Read-while-write functionality
gives more flexibility in data output from the device. The data read from the chip depends on the Partition Address applied
to the device. Depending on the command issued to the chip, each partition is placed into one of the following three
output states during commands: Read Array, Read Status or Read ID/CFI. This partition's output state is retained until a

new command is issued to the chip at that Partition Address. This allows the user to set partition #1's output state to Read
Array, and partition #4's output state to Read Status. Each time the partition address is changed to partition #4 (without
issuing a new command), the Status will be read from the chip.
Illegal commands include commands outside of the allowed command set (allowed commands: 41H [pgm], 20H [erase],
etc.)
All partitions default to Read Array on powerup.
If a Read Array is attempted from a busy partition, the result is unreliable data. When the user returns to this partition
address later, the output mux will be in the “Read Array” state from its last visit. the Read ID and Read Query commands
perform the same function in the device. The ID and Query data are located at different locations in the address map.
1st and 2nd cycles of "2 cycles write commands" must be given to the same partition address, or unexpected results will
occur.
The Clear Status command clears only the error bits in the status register if the device is not in the following modes: 1)
WSM running (Pgm Busy, Erase Busy, Pgm Busy In Erase Suspend, OTP Busy, BEFP modes) 2) Suspend states (Erase
Suspend, Pgm Suspend, Pgm Suspend In Erase Suspend).
BEFP writes are allowed only when the status register bit #0 = 0 or else the data is ignored.
The current state is that of the chip and not of the partition. Each partition remembers which output (Array, ID/CFI or
Status) it was last pointed to on the last instruction to the chip, but the next state of the chip does not depend on where
the partition's output mux is presently pointing to.
Confirm commands (Lock Block, Unlock Block, Lock-Down Block, Configuration Register and Blank Check) perform the
operation and then move to the Ready State.
Buffered programming will botch when a different block address (as compared to address given with E9 command) is
written during the BP Load1 and BP Load2 states.
WA0 refers to the block address latched during the first write cycle of the current operation.
All two cycle commands are considered as a contiguous whole during device suspend states. Individual commands are not
parsed separately; that is, the 2nd cycle of an erase command issued in program suspend will NOT resume the program
operation.
The Buffered Program setup command (0xE9) will not change the partition state. The Buffered Program Confirm command
(0xD0) will place the partition in read status mode.
Appendix A AADM Mode
A.1
AADM Feature Overview
The following is a list of general requirements for AADM mode. Additional details can be
found in subsequent sections.
• Feature Availability: AADM mode is available in devices that are configured as A/
D MUX. With this configuration, AADM mode is enabled by setting a specific volatile
bit in the RCR.
• High Address Caputure (A[MAX:16]): When AADM mode is enabled,
A[MAX:16] and A[15:0] are captured from the A/DQ[15:0] balls. The selection of
A[MAX:16] or A[15:0] is determined by the state of the OE# input, as A[MAX:16]
is captured when OE# is at VIL.
• Read & Write Cycle Support: In AADM mode, both asynchronous and
synchronous Cycles are supported.
• Customer Requirements: For AADM operation, the customer is required to
ground A16-Amax.
• Other Characteristics: For AADM, all other device characteristics (pgm time,
erase time, ICCS, etc.) are the same as A/D MUX unless otherwise stated.
A.2
AADM Mode Enable (RCR[4]=1)
Setting RCR.4 to its non-default state (‘1b) enables AADM mode:
• The default device configuration upon Reset or Powerup is A/D MUX Mode
• Upon setting RCR[4]=1, the upper Addresses A[max:16] are latched as all 0’s by
default.

A.3
Bus Cycles and Address Capture
AADM bus operations have one or two address cycles. For two address cycles, the
upper address (A[MAX:16]) must be issued first, followed by the lower address
(A[15:0]). For bus operations with only one address cycle, only the lower address is
issued. The upper address that applies is the one that was most recently latched on a
previous bus cycle. For all read cycles, sensing begins when the lower address is
latched, regardless of whether there are one or two address cycles.
In bus cycles, the external signal that distinguishes the upper address from the lower
address is OE#. When OE# is at VIH, a lower address is captured; when OE# is at VIL,
an upper address is captured.
When the bus cycle has only one address cycle, the timing waveform is similar to A/D
MUX mode. The lower address is latched when OE# is at VIH, and data is subsequently
outputted after the falling edge of OE#.
Note:
When the device initially enters AADM mode, the upper address is internally latched as
all 0’s.
A.3.1
WAIT Behavior
The WAIT behavior in AADM mode functions the same as the legacy M18 non-MUX
WAIT behavior (ADMux WAIT behavior is unique). In other words, WAIT will always be
driven whenever DQ[15:0] is driven, and WAIT will tri-state whenever DQ[15:0] tristate. In asynchronous mode (RCR[15] = ‘1b), WAIT always indicates “valid data”
when driven. In synchronous mode (RCR[15] = ‘0b), WAIT indicates “valid data” only
after the latency count has lapsed and the data output data is truly valid.
A.3.2
Asynchronous Read and Write Cycles
For asynchronous read and write cycles, ADV# must be toggled high-low-high a
minimum of one time and a maximum of two times during a bus cycle. If ADV# is
toggled low twice during a bus cycle, OE# must be held low for the first ADV# rising
edge and OE# must be held high for the second ADV# rising edge. The first ADV#
rising edge (with OE# low) captures A[MAX:16]. The second ADV# rising edge (with
OE# high) captures A[15:0]. Each bus cycle must toggle ADV# high-low-high at least
one time in order to capture A[15:0]. For asynchronous reads, sensing begins when the
lower address is latched.
During asynchronous cycles, it is optional to capture A[MAX:16]. If these addresses are
not captured, then the previously captured A[MAX:16] contents will be used.
A.3.2.1
Asynchronous Read Cycles
For asynchronous read and latching specifications, refer to Table 63, “AADM
Aynchronous and Latching Timings” on page 130. For asynchronous read timing
diagrams, refer to Figure 61, “AADM Asynchronous Read Cycle (Latching A[MAX:0])”
on page 130 and Figure 62, “AADM Asynchronous Read Cycle (Latching A[15:0] only)”
on page 131. For AADM, note that asynchronous read access is from the rising edge of
ADV# rather than the falling edge. (i.e. TVHQV rather than TVLQV)

A.3.3
Synchronous Read and Write Cycles
Just as asynchronous bus cycles, synchronous bus cycles (RCR[15] = ‘0b) can have
one or two address cycles. If the are two address cycles, the upper address must be
latched first with OE# at VIL followed by the lower address with OE# at VIH. If there is
only one address cycle, only the lower address will be latched and the previously
latched upper address applies. For reads, sensing begins when the lower address is
latched, but for synchronous reads, addresses are latched on a rising clock CLK instead
of a rising ADV# edge.
For synchronous bus cycles with two address cycles, it is not necessary to de-assert
ADV# between the two address cycles. This allows both the upper and lower address to
be latched in only two clock periods.
A.3.3.1
Synchronous Read Cycles
For synchronous read specifications, refer to Table 65, “AADM Synchronous Timings” on
page 133. For synchronous read timing diagrams, refer to the following:
• Figure 65, “AADM Sync Burst Read Cycle (ADV# De-asserted between Address
Cycles)” on page 134
• Figure 66, “AADM Sync Burst Read Cycle (ADV# Not De-asserted between Address
Cycles)” on page 134

Notes:
1.
The device must operate down to 9.6MHz in synchronous burst mode.
2.
During the address capture phase of a read burst bus cycle, OE# timings relative to CLK shall be identical to those of
ADV# relative to CLK.
3.
In synchronous burst read cycles, the asynchronous OE# to ADV# setup and hold times must also be met (Tghvh & Tvhgl)
to signify that the address capture phase of the bus cycle is complete.
4.
To prevent A/D bus contention between the host and the memory device, OE# may only be asserted low after the host has
satisfied the ADDR hold spec, Tchax.
5.
Rise and fall time specified between Vil & Vih
6.
A read cycle may only be terminated (prior to the completion of sensing data) one time before a full bus cycle must be
allowed to complete.

Synchronous Write Cycles
For synchronous writes, only the address latching cycle(s) are synchronous.
Synchronous address latching is depicted in the timing diagrams for synchronous read
cycles:
• Figure 65, “AADM Sync Burst Read Cycle (ADV# De-asserted between Address
Cycles)” on page 134
• Figure 66, “AADM Sync Burst Read Cycle (ADV# Not De-asserted between Address
Cycles)” on page 134
• Figure 67, “AADM Sync Burst Read Cycle (Latching A[15:0] only)” on page 135
The actual write operation (rising WE# edge) is asynchronous and is independent of
CLK. Asynchronous writes are depicted in the timing diagrams for asynchronous write
cycles:
• Figure 63, “AADM Asynchronous Write Cycle (Latching A[MAX:0])” on page 132
• Figure 64, “AADM Asynchronous Write Cycle (Latching A[15:0] only)” on page 132
A.3.5
System Boot
Systems that use the AADM mode will boot from the bottom 128k Bytes of device
memory because A[MAX:16] are expected to be grounded in-system. The 128k Byte
boot region is sufficient to perform required boot activities before setting RCR[4] to
enable AADM mode.
