Description
Description
The NAND08GW3C2A and NAND16GW3C2A are multilevel cell (MLC) devices from the
NAND Flash 2112-byte page family of non-volatile Flash memories. The NAND08GW3C2A
and the NAND16GW3C2A have a density of 8- and 16-Gbit, respectively. The
NAND16GW3C2A is composed of two 8-Gbit dice; each die can be accessed independently
using two Chip Enable and two Ready/Busy signals. The devices operate from a 3 V VDD
power supply.
The address lines are multiplexed with the Data Input/Output signals on a multiplexed x8
input/output bus. This interface reduces the pin count and makes it possible to migrate to
other densities without changing the footprint.
Each block can be programmed and erased over 10,000 cycles (with ECC on). The device
also has hardware security features; a write protect pin is available to give hardware
protection against Program and Erase operations.
The devices feature an open-drain, ready/busy output that can be used to identify if the
Program/Erase/Read (P/E/R) Controller is currently active. The use of an open-drain output
allows the ready/busy pins of several memories to be connected to a single pull-up resistor.
The memory array is split into 2 planes of 2048 blocks each. This multiplane architecture
makes it possible to program 2 pages at a time (one in each plane) or to erase 2 blocks at a
time (one in each plane), dividing by two the average program and erase times.
The devices have the Chip Enable “Don’t Care” feature, which allows code to be directly
downloaded by a microcontroller, as Chip Enable transitions during the latency time do not
stop the Read operation.
There is the option of a unique identifier (serial number), which allows the
NAND08GW3C2A and the NAND16GW3C2A to be uniquely identified. It is subject to an
NDA (non-disclosure agreement) and is, therefore, not described in the datasheet. For more
details of this option contact your nearest Numonyx Sales office.
The devices are available in TSOP48 (12 × 20 mm) and LGA52 (12 x 17 x 0.65 mm)
packages. To meet environmental requirements, Numonyx offers the devices in ECOPACK®
packages. ECOPACK packages are lead-free. In compliance with JEDEC Standard
JESD97, the category of second level interconnect is marked on the package and on the

Memory array organization
Memory array organization
The memory array is comprised of NAND structures where 32 cells are connected in series.
The memory array is organized in blocks where each block contains 128 pages. The array is
split into two areas, the main area and the spare area. The main area of the array is used to
store data, whereas the spare area is typically used to store software flags or bad block
identification.
The pages are split into a 2048-byte main area and a spare area of 64 bytes. Refer to
Figure 6: Memory array organization.
2.1
Bad blocks
The NAND08GW3C2A and NAND16GW3C2A devices may contain bad blocks, where the
reliability of blocks that contain one or more invalid bits is not guaranteed. Additional bad
blocks may develop during the lifetime of the device.
The bad block Information is written prior to shipping (refer to Section 9.1: Bad block
management for more details).
Table 3: Valid blocks shows the minimum number of valid blocks in each device. The values
shown include both the bad blocks that are present when the device is shipped and the bad
blocks that could develop later on.
These blocks need to be managed using Bad Blocks Management and Block Replacement
(refer to Section 9: Software algorithms).

Signal descriptions
Signal descriptions
See Figure 1: Logic block diagram, and Table 2: Signal names, for a brief overview of the
signals connected to this device.
3.1
Inputs/outputs (I/O0-I/O7)
Input/outputs 0 to 7 are used to input the selected address, output the data during a Read
operation, or input a command or data during a Write operation. The inputs are latched on
the rising edge of Write Enable. I/O0-I/O7 are left floating when the device is deselected or
the outputs are disabled.
3.2
Address Latch Enable (AL)
The Address Latch Enable activates the latching of the address inputs in the command
interface. When AL is High, the inputs are latched on the rising edge of Write Enable.
3.3
Command Latch Enable (CL)
The Command Latch Enable activates the latching of the command inputs in the command
interface. When CL is High, the inputs are latched on the rising edge of Write Enable.
3.4
Chip Enable (E1, E2)
The Chip Enable input activates the memory control logic, input buffers, decoders and
sense amplifiers. When Chip Enable is Low, VIL, the device is selected. If Chip Enable goes
High, vIH, while the device is busy, the device remains selected and does not go into standby
mode.
E2 is only available on the NAND16GW3C4A.
3.5
Read Enable (R)
The Read Enable pin, R, controls the sequential data output during Read operations. Data
is valid tRLQV after the falling edge of R. The falling edge of R also increments the internal
column address counter by one.
3.6
Write Enable (W)
The Write Enable input, W, controls writing to the command interface, input address and
data latches. Both addresses and data are latched on the rising edge of Write Enable.
During power-up and power-down a recovery time of 10 µs (min) is required before the
command interface is ready to accept a command. It is recommended to keep Write Enable
High during the recovery time.
15/58
Signal descriptions
3.7
NAND08GW3C2A, NAND16GW3C2A
Write Protect (WP)
The Write Protect pin is an input that gives a hardware protection against unwanted
Program or Erase operations. When Write Protect is Low, VIL, the device does not accept
any Program or Erase operations.
It is recommended to keep the Write Protect pin Low, VIL, during power-up and power-down.
3.8
Ready/Busy (RB1, RB2)
The Ready/Busy output, RB, is an open-drain output that can be used to identify if the P/E/R
controller is currently active.
When Ready/Busy is Low, VOL, a Read, Program or Erase operation is in progress. When
the operation completes, Ready/Busy goes High, VOH.
The use of an open-drain output allows the Ready/Busy pins from several memories to be
connected to a single pull-up resistor. A Low will then indicate that one, or more, of the
memories is busy.
During power-up and power-down a minimum recovery time of 10 µs is required before the
command interface is ready to accept a command. During this period the Ready/Busy signal
is Low, VOL.
RB2 is only available on the NAND16GW3C4A.
Refer to Section 12.1: Ready/Busy signal electrical characteristics for details on how to
calculate the value of the pull-up resistor.
3.9
VDD supply voltage
VDD provides the power supply to the internal core of the memory device. It is the main
power supply for operations (Read, Program and Erase).
3.10
VSS ground
Ground, VSS, is the reference for the power supply. It must be connected to the system
ground.

Bus operations
Bus operations
There are six standard bus operations that control the memory. Each of these is described
in this section. See the summary in Table 4: Bus operations.
Typically, glitches of less than 5 ns on Chip Enable, Write Enable and Read Enable are
ignored by the memory and do not affect bus operations.
4.1
Command Input
Command Input bus operations are used to give commands to the memory. Commands are
accepted when Chip Enable is Low, Command Latch Enable is High, Address Latch Enable
is Low and Read Enable is High. They are latched on the rising edge of the Write Enable
signal.
Only I/O0 to I/O7 are used to input commands.
See Figure 16 and Table 20 for details of the timings requirements.
4.2
Address Input
Address Input bus operations are used to input the memory addresses. Five bus cycles are
required to input the addresses (refer to Table 5: Address insertion).
The addresses are accepted when Chip Enable is Low, Address Latch Enable is High,
Command Latch Enable is Low and Read Enable is High. They are latched on the rising
edge of the Write Enable signal. Only I/O0 to I/O7 are used to input addresses.
See Figure 17 and Table 20 for details of the timings requirements.
4.3
Data Input
Data Input bus operations are used to input the data to be programmed. Data is only
accepted when Chip Enable is Low, Address Latch Enable is Low, Command Latch Enable
is Low and Read Enable is High. The data is latched on the rising edge of the Write Enable
signal. The data is input sequentially using the Write Enable signal.
See Figure 18 and Table 20 for details of the timing requirements.
4.4
Data Output
Data Output bus operations are used to read: the data in the memory array, the status
register, the electronic signature and the unique identifier.
Data is output when Chip Enable is Low, Write Enable is High, Address Latch Enable is Low,
and Command Latch Enable is Low.
The data is output sequentially using the Read Enable signal.
If the Read Enable pulse frequency is lower then 33 MHz (tRLRL higher than 30 ns), the
output data is latched on the rising edge of Read Enable signal (see Figure 19).
17/58
Bus operations
NAND08GW3C2A, NAND16GW3C2A
For higher frequencies (tRLRL lower than 30 ns), the Extended Data Out (EDO) mode must
be considered. In this mode, data output is valid on the input/output bus for a time of tRLQX
after the falling edge of Read Enable signal (see Figure 20).
See Table 21 for details on the timings requirements.
4.5
Write Protect
Write Protect bus operations are used to protect the memory against Program or Erase
operations. When the Write Protect signal is Low the device does not accept Program or
Erase operations, therefore, the contents of the memory array cannot be altered. The Write
Protect signal is not latched by Write Enable to ensure protection, even during power-up.
4.6
Standby
The memory enters Standby mode by driving Chip Enable, E, High. In Standby mode, the
device is deselected, outputs are disabled and power consumption is reduced.

Command set
All bus write operations to the device are interpreted by the command interface. The
commands are input on I/O0-I/O7 and are latched on the rising edge of Write Enable when
the Command Latch Enable signal is High. Device operations are selected by writing
specific commands to the Command Register. The two-step command sequences for
Program and Erase operations are imposed to maximize data security.
The commands are summarized in Table 7: Commands.

Device operations
Device operations
This section gives the details of the device operations.
6.1
Read Memory Array
At power-up the device defaults to Read mode. To enter Read mode from another mode the
Read command must be issued, see Table 7: Commands. Once a Read command is
issued, subsequent consecutive Read commands only require the confirm command code
(30h).
Once a Read command is issued, two types of operations are available: Random Read and
Page Read.
6.2
Random Read
Each time the Read command is issued, the first read is random-read.
6.3
Page Read
After the first random read access, the page data (2112 bytes) is transferred to the page
buffer in a time of tWHBH (refer to Table 21 for value). Once the transfer is complete, the
Ready/Busy signal goes High. The data can then be read out sequentially (from the
selected column address to last column address) by pulsing the Read Enable signal.
The device can output random data in a page, instead of the consecutive sequential data, by
issuing a Random Data Output command. The Random Data Output command can be used
to skip some data during a sequential data output.
The sequential operation can be resumed by changing the column address of the next data
to be output, to the address which follows the Random Data Output command.The Random
Data Output command can be issued as many times as required within a page.

Page Program
The Page Program operation is the standard operation to program data to the memory
array. Generally, data is programmed sequentially, however, the device does support
random input within a page.
The memory array is programmed by page, however, partial page programming is allowed
where any number of bytes (1 to 2112) can be programmed.
Only one consecutive partial Page Program operation is allowed on the same page. After
exceeding this a Block Erase command must be issued before any further Program
operations can take place in that page.
23/58
Device operations
6.5
NAND08GW3C2A, NAND16GW3C2A
Sequential Input
To input data sequentially the addresses must be sequential and remain in one block.
For Sequential Input, each Page Program operation comprises five steps:
6.6
1.
One bus cycle is required to set up the Page Program (Sequential Input) command
(see Table 7).
2.
Five bus cycles are then required to input the program address (refer to Table 5).
3.
The data is loaded into the data registers.
4.
One bus cycle is required to issue the Page Program Confirm command to start the
P/E/R controller. The P/E/R only starts if the data has been loaded in step 3.
5.
The P/E/R controller then programs the data into the array.
Random Data Input
During a Sequential Input operation, the next sequential address to be programmed can be
replaced by a random address issuing a Random Data Input command. The following two
steps are required to issue the command:
1.
One bus cycle is required to setup the Random Data Input command (see Table 7).
2.
Two bus cycles are then required to input the new column address (refer to Table 5).
Random Data Input can be repeated as often as required in any given page.
Once the Program operation has started the Status Register can be read using the Read
Status Register command. During program operations the status register only flags errors
for bits set to ‘1’ that have not been successfully programmed to ‘0’.
During the Program operation, only the Read Status Register and Reset commands are
accepted; all other commands are ignored. Once the Program operation has completed, the
P/E/R controller bit SR6 is set to ‘1’ and the Ready/Busy signal goes High.
The device remains in Read Status Register mode until another valid command is written to
the command interface.

Multiplane Page Program
The devices support Multiplane Page Program, that allows the programming of two pages in
parallel, one in each plane.
A Multiplane Page Program operation requires two steps:
1.
The first step loads serially up to two pages of data (4224 bytes) into the data buffer. It
requires:
–
One clock cycle to set up the Page Program command (see Section 6.5:
Sequential Input).
–
Five bus write cycles to input the first page address and data. The address of the
first page must be within the first plane (A19 = 0).
–
One bus write cycle to issue the Page Program Confirm code. After this the device
is busy for a time of tBLBH5.
–
When the device returns to the ready state (Ready/Busy High), a Multiplane Page
Program Setup code must be issued, followed by the second page address (5
write cycles) and data. The address of the second page must be within the second
plane (A19=1), and A18 to A12 must be the address bits loaded during the first
address insertion.
25/58
Device operations
2.
NAND08GW3C2A, NAND16GW3C2A
The second step programs, in parallel, the two pages of data loaded into the data buffer
into the appropriate memory pages. It is started by issuing a Program Confirm
command.
As for standard Page Program operations, the device supports Random Data Input during
both data loading phases.
Once the Multiplane Page Program operation has started, maintaining a delay of tBLBH5, the
Status Register can be read using the Read Status Register command. Once the Multiplane
Page Program operation has completed, the P/E/R controller bit SR6 is set to ‘1’ and the
Ready/Busy signal goes High.
If the Multiplane Page Program fails, an error is signaled on bit SR0 of the Status Register.
However, there is no way to identify for which page the program operation failed.
See Figure 11 for a description of Multiplane Page Program waveforms.

Block Erase
Erase operations are done one block at a time. An Erase operation sets all of the bits in the
addressed block to ‘1’. All previous data in the block is lost.
An Erase operation consists of three steps (refer to Figure 12):
1.
One bus cycle is required to setup the Block Erase command. Only addresses A19 to
A31 are used; the other address inputs are ignored.
2.
Three bus cycles are then required to load the address of the block to be erased. Refer
to Table 6 for the block addresses of each device.
3.
One bus cycle is required to issue the Block Erase Confirm command to start the P/E/R
controller.
The Erase operation is initiated on the rising edge of write Enable, W, after the Confirm
command is issued. The P/E/R Controller handles Block Erase and implements the verify
process.
During the Block Erase operation, only the Read Status Register and Reset commands are
accepted; all other commands are ignored.

Device operations
Once the program operation has completed, the P/E/R controller bit SR6 is set to ‘1’ and the

Multiplane Block Erase
The Multiplane Block Erase operation allows erasing two blocks in parallel, one in each
plane. It consists of three steps (refer to Figure 13: Multiplane Block Erase operation):
1.
Eight bus cycles are required to set up the Block Erase command and load the
addresses of the blocks to be erased. The Setup command, followed by the address of
the block to be erased, must be issued for each block. No dummy busy time is required
between the first and second block address insertion. As for Multiplane Page Program,
the address of the first and second page must be within the first plane (A19 = 0) and
second plane (A19 = 1), respectively.
2.
One bus cycle is then required to issue the Multiplane Block Erase confirm command
and start the P/E/R controller.
If the Multiplane Block Erase fails, an error is signaled on bit SR0 of the status register.
However, there is no way to identify for which page the Multiplane Block Erase operation
failed.

Reset
The Reset command is used to reset the command interface and Status Register. If the
Reset command is issued during any operation, the operation is aborted. If it is a Program
or Erase operation that is being aborted, the contents of the memory locations being
modified are no longer valid as the data is partially programmed or erased.
If the device has already been reset, then the new Reset command is not accepted.
The Ready/Busy signal goes Low for tBLBH4 after the Reset command is issued. The value
of tBLBH4 depends on the operation that the device was performing when the command was
issued. Refer to Table 21 for the values.
6.11
Read Status Register
The device contains a Status Register that provides information on the current or previous
Program or Erase operation. The various bits in the Status Register convey information and
errors on the operation.
The Status Register is read by issuing the Read Status Register command. The Status
Register information is present on the output data bus (I/O0-I/O7) on the falling edge of Chip
Enable or Read Enable, whichever occurs last. When several memories are connected in a
system, the use of Chip Enable and Read Enable signals allows the system to poll each
device separately, even when the Ready/Busy pins are common-wired. It is not necessary to
toggle the Chip Enable or Read Enable signals to update the contents of the status register.
After the Read Status Register command has been issued, the device remains in Read
Status Register mode until another command is issued. Therefore, if a Read Status Register
command is issued during a random read cycle a new Read command must be issued to
continue with a Page Read operation.
Refer to Table 8 which summarizes Status Register bits and should be read in conjunction
with the following text descriptions.
6.11.1
Write protection bit (SR7)
The write protection bit can identify if the device is protected or not. If the write protection bit
is set to ‘1’ the device is not protected and Program or Erase operations are allowed. If the
write protection bit is set to ‘0’ the device is protected and Program or Erase operations are
not allowed.
6.11.2
P/E/R controller bit (SR6)
Status register bit SR6 acts as a P/E/R controller bit, which indicates whether the P/E/R
controller is active or inactive. When the P/E/R controller bit is set to ‘0’, the P/E/R controller
is active (device is busy); when the bit is set to ‘1’, the P/E/R controller is inactive (device is
ready).
6.11.3
Error bit (SR0)
The error bit is used to identify if any errors have been detected by the P/E/R controller. The
error bit is set to ‘1’ when a Program or Erase operation has failed to write the correct data to
the memory. If the error bit is set to ‘0’, the operation has completed successfully.

NAND08GW3C2A, NAND16GW3C2A
Concurrent operations and ERS on the
NAND16GW3C2A
The NAND16GW3C2A is composed by two 8-Gbit dice stacked together. This configuration
allows the device to support concurrent operations. This means that while performing an
operation in one die (Erase, Read, Program, etc.), another operation is possible in the other
die.
The standard Read Status Register (ERS) operation returns the status of the
NAND16GW3C2A device. To provide information on each 8-Gbit die, the NAND16GW3C2A
features an Extended Read Status Register command that allows to check independently
the status of each die.
The following steps are required to perform concurrent operations:
1.
Select one of the two dice by setting the most significant address bit A31 to ‘0’ or ‘1’.
2.
Execute one operation on this die.
3.
Launch a concurrent operation on the other die.
4.
Check the status of these operations by performing an Extended Read Status Register
operation.
All combinations of operations are possible except executing Read on both dice. This is due
to the fact that the input/output bus is common to both dice.
Refer to Table 13 for the description of the Extended Read Status Register command
sequence, and to Table 8. for the definition of the Status Register bits.

Data protection
Data protection
The device has hardware features to protect against Program and Erase operations. It
features a Write Protect, WP, pin, which protects the device against program and erase
operations. It is recommended to keep WP at VIL during power-up and power-down.

Software algorithms
This section gives information on the software algorithms that Numonyx recommends
implementing to manage the bad blocks and extend the lifetime of the NAND device.
NAND Flash memories are programmed and erased by Fowler-Nordheim tunneling using
high voltage. Exposing the device to high voltage for extended periods can cause the oxide
layer to be damaged. For this reason, the number of program and erase cycles is limited
(see Table 15 for value). It is recommended to implement garbage collection, wear-leveling
and error correction code algorithms to extend the number of program and erase cycles and
to increase data retention.
To help integrate a NAND memory into an application Numonyx can provide a File System
OS Native reference software, which supports the basic commands of file management.
Contact the nearest Numonyx sales office for more details.
9.1
Bad block management
Devices with bad blocks have the same quality level and the same AC and DC
characteristics as devices where all the blocks are valid. A bad block does not affect the
performance of valid blocks because it is isolated from the bit line and common source line
by a select transistor.
The devices are supplied with all the locations inside valid blocks erased (FFh). The bad
block information is written prior to shipping. Any block, where the 1st byte in the spare area
of the last page, does not contain FFh, is a bad block.
The bad block information must be read before any erase is attempted as the bad block
Information may be erased. For the system to be able to recognize the bad blocks based on
the original information it is recommended to create a bad block table following the flowchart
shown in Figure 14.

9.2
NAND08GW3C2A, NAND16GW3C2A
NAND Flash memory failure modes
The NAND08GW3C2A and NAND16GW3C2A devices may contain bad blocks, where the
reliability of blocks that contain one or more invalid bits is not guaranteed. Additional bad
blocks may develop during the lifetime of the device.
To implement a highly reliable system, all the possible failure modes must be considered:
●
Program/erase failure
in this case, the block has to be replaced by copying the data to a valid block. These
additional bad blocks can be identified as attempts to program or erase them and will
give errors in the Status Register.
Because the failure of a Page Program operation does not affect the data in other
pages in the same block, the block can be replaced by re-programming the current data
and copying the rest of the replaced block to an available valid block. The Copy Back
Program command can be used to copy the data to a valid block. See Section Figure
10.: Random Data Input during Sequential Data Input for more details.
●
Read failure
in this case, ECC correction must be implemented. To efficiently use the memory
space, it is recommended to recover single-bit errors in read by ECC, without replacing
the whole block.
Refer to Table 14 for the procedure to follow if an error occurs during an operation.

Garbage collection
When a data page needs to be modified, it is faster to write to the first available page and
mark the previous page as invalid. After several updates it is necessary to remove invalid
pages to free some memory space.
To free this memory space and allow further program operations, it is recommended to
implement a garbage collection algorithm. In a garbage collection software the valid pages
are copied into a free area and the block containing the invalid pages is erased (see
Figure 15).

9.4
NAND08GW3C2A, NAND16GW3C2A
Wear-leveling algorithm
For write-intensive applications, it is recommended to implement a wear-leveling algorithm
to monitor and spread the number of write cycles per block.
In memories that do not use a wear-leveling algorithm, not all blocks get used at the same
rate. The wear-leveling algorithm ensures that equal use is made of all the available write
cycles for each block.
There are two wear-leveling levels:
1.
First level wear-leveling, where new data is programmed to the free blocks that have
had the fewest write cycles
2.
Second level wear-leveling, where long-lived data is copied to another block so that the
original block can be used for more frequently changed data.
The second level wear-leveling is triggered when the difference between the maximum and
the minimum number of write cycles per block reaches a specific threshold.

Hardware simulation models
9.5.1
Behavioral simulation models
Software algorithms
Denali Software Corporation models are platform-independent functional models designed
to assist customers in performing entire system simulations (typical VHDL/Verilog). These
models describe the logic behavior and timings of NAND Flash devices, and, therefore,
allow software to be developed before hardware.
9.5.2
IBIS simulations models
I/O buffer information specification (IBIS) models describe the behavior of the I/O buffers
and electrical characteristics of Flash devices.
These models provide information such as AC characteristics, rise/fall times, and package
mechanical data, all of which are measured or simulated at voltage and temperature ranges
wider than those allowed by target specifications.
IBIS models are used to simulate PCB connections and can be used to resolve compatibility
issues when upgrading devices. They can be imported into SPICETOOLS.

Ready/Busy signal electrical characteristics
Figure 30, Figure 29 and Figure 31 show the electrical characteristics for the Ready/Busy
signal. The value required for the resistor RP can be calculated using the following equation:
(V
–
)
DDmax V OLmax
R P min = ------------------------------------------------------------I OL + I L
So,
3.2V
R P min = -------------------------8mA + I L
where IL is the sum of the input currents of all the devices tied to the Ready/Busy signal. RP
max is determined by the maximum value of tr.

Data protection
The Numonyx NAND device is designed to guarantee data protection during power
transitions.
A VDD detection circuit disables all NAND operations, if VDD is below the VLKO threshold.
In the VDD range from VLKO to the lower limit of nominal range, the WP pin should be kept
Low (VIL) to guarantee hardware protection during power transitions as shown in Figure 32.
