SUMMARY DESCRIPTION
The NAND Flash 528 Byte/ 264 Word Page is a
family of non-volatile Flash memories that uses
the Single Level Cell (SLC) NAND cell technology.
It is referred to as the Small Page family. The devices range from 128Mbits to 1Gbit and operate
with either a 1.8V or 3V voltage supply. The size of
a Page is either 528 Bytes (512 + 16 spare) or 264
Words (256 + 8 spare) depending on whether the
device has a x8 or x16 bus width.
The address lines are multiplexed with the Data Input/Output signals on a multiplexed x8 or x16 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
100,000 cycles. To extend the lifetime of NAND
Flash devices it is strongly recommended to implement an Error Correction Code (ECC). A Write
Protect pin is available to give a 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 from several memories to be connected
to a single pull-up resistor.
A Copy Back command is available to optimize the
management of defective blocks. When a Page
Program operation fails, the data can be programmed in another page without having to resend the data to be programmed.
The devices are available in the following packages:
■
TSOP48 12 x 20mm for all products
■
USOP48 12 x 17 x 0.65mm for 128Mb, 256Mb
and 512Mb products
■
VFBGA55 (8 x 10 x 1mm, 6 x 8 ball array,
0.8mm pitch) for 128Mb and 256Mb products
■
TFBGA55 (8 x 10 x 1.2mm, 6 x 8 ball array,
0.8mm pitch) for 512Mb Dual Die product
■
VFBGA63 (9 x 11 x 1mm, 6 x 8 ball array,
0.8mm pitch) for the 512Mb product
■
TFBGA63 (9 x 11 x 1.2mm, 6 x 8 ball array,
0.8mm pitch) for the 1Gb Dual Die product
Two options are available for the NAND Flash
family:
Chip Enable Don’t Care, which allows code to be
directly downloaded by a microcontroller, as Chip
Enable transitions during the latency time do not
stop the read operation.
A Serial Number, which allows each device to be
uniquely identified. The Serial Number options is
subject to an NDA (Non Disclosure Agreement)
and so not described in the datasheet. For more
details of this option contact your nearest ST Sales
office.
For information on how to order these options refer
to Table 28., Ordering Information Scheme. Devices are shipped from the factory with Block 0 always valid and the memory content bits, in valid
blocks, erased to ’1’.
See Table 2., Product Description, for all the devices available in the family.

MEMORY ARRAY ORGANIZATION
The memory array is made up of NAND structures
where 16 cells are connected in series.
The memory array is organized in blocks where
each block contains 32 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
Error correction Codes, software flags or Bad
Block identification.
In x8 devices the pages are split into a main area
with two half pages of 256 Bytes each and a spare
area of 16 Bytes. In the x16 devices the pages are
split into a 256 Word main area and an 8 Word
spare area. Refer to Figure 10., Memory Array Organization.
The Bad Block Information is written prior to shipping (refer to Bad Block Management section for
more details).
Table 4. 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, Block Replacement or Error
Correction Codes (refer to SOFTWARE ALGORITHMS section).

Bad Blocks
The NAND Flash 528 Byte/ 264 Word Page devices may contain Bad Blocks, that is blocks that contain one or more invalid bits whose reliability is not
guaranteed. Additional Bad Blocks may develop
during the lifetime of the device.

SIGNAL DESCRIPTIONS
See Figure 2., Logic Diagram, and Table
3., Signal Names, for a brief overview of the signals connected to this device.
tions. Data is valid tRLQV after the falling edge of R.
The falling edge of R also increments the internal
column address counter by one.
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.
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 1µs (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.
Inputs/Outputs (I/O8-I/O15). Input/Outputs 8 to
15 are only available in x16 devices. They are
used to output the data during a Read operation or
input data during a Write operation. Command and
Address Inputs only require I/O0 to I/O7.
The inputs are latched on the rising edge of Write
Enable. I/O8-I/O15 are left floating when the device is deselected or the outputs are disabled.
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.
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.
Chip Enable (E). 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.
While the device is busy programming or erasing,
Chip Enable transitions to High, VIH, are ignored
and the device does not revert to the Standby
mode.
While the device is busy reading:
■
the Chip Enable input should be held Low
during the whole busy time (tBLBH1) for
devices that do not present the Chip Enable
Don’t Care option. Otherwise, the read
operation in progress is interrupted and the
device reverts to the Standby mode.
■
for devices that feature the Chip Enable Don't
Care option, Chip Enable going High during
the busy time (tBLBH1) will not interrupt the
read operation and the device will not revert to
the Standby mode.
Read Enable (R). The Read Enable, R, controls
the sequential data output during Read opera-
16/57
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.
Ready/Busy (RB). 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.
Refer to the Ready/Busy Signal Electrical Characteristics section for details on how to calculate the
value of the pull-up resistor.
VDD Supply Voltage. VDD provides the power
supply to the internal core of the memory device.
It is the main power supply for all operations (read,
program and erase).
An internal voltage detector disables all functions
whenever VDD is below 2.5V (for 3V devices) or
1.5V (for 1.8V devices) to protect the device from
any involuntary program/erase during power-transitions.
Each device in a system should have VDD decoupled with a 0.1µF capacitor. The PCB track widths
should be sufficient to carry the required program
and erase currents
VSS Ground. Ground, VSS, is the reference for
the power supply. It must be connected to the system ground.

BUS OPERATIONS
There are six standard bus operations that control
the memory. Each of these is described in this
section, see Table 5., Bus Operations, for a summary.
Command Input
Command Input bus operations are used to give
commands to the memory. Command 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 23. and Table 20. for details of the timings requirements.
Address Input
Address Input bus operations are used to input the
memory address. Three bus cycles are required to
input the addresses for the 128Mb and 256Mb devices and four bus cycles are required to input the
addresses for the 512Mb and 1Gb devices (refer
to Tables 6 and 7, 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 24. and Table 20. for details of the timings requirements.
Data is accepted only 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 25. and Table 20. and Table 21. for details of the timings requirements.
Data Output
Data Output bus operations are used to read: the
data in the memory array, the Status Register, the
Electronic Signature and the Serial Number.
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.
See Figure 26. and Table 21. for details of the timings requirements.
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
will not accept program or erase operations and so
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.
Standby
Data Input
Data Input bus operations are used to input the
data to be programmed.
When Chip Enable is High the memory enters
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 Com-
mand Register. The two-step command
sequences for program and erase operations are
imposed to maximize data security.
The Commands are summarized in Table

DEVICE OPERATIONS
Pointer Operations
As the NAND Flash memories contain two different areas for x16 devices and three different areas
for x8 devices (see Figure 11.) the read command
codes (00h, 01h, 50h) are used to act as pointers
to the different areas of the memory array (they select the most significant column address).
The Read A and Read B commands act as pointers to the main memory area. Their use depends
on the bus width of the device.
■
In x16 devices the Read A command (00h)
sets the pointer to Area A (the whole of the
main area) that is Words 0 to 255.
■
In x8 devices the Read A command (00h) sets
the pointer to Area A (the first half of the main
area) that is Bytes 0 to 255, and the Read B
command (01h) sets the pointer to Area B (the
second half of the main area) that is Bytes 256
to 511.
In both the x8 and x16 devices the Read C command (50h), acts as a pointer to Area C (the spare
memory area) that is Bytes 512 to 527 or Words
256 to 263.
Once the Read A and Read C commands have
been issued the pointer remains in the respective
areas until another pointer code is issued. However, the Read B command is effective for only one
operation, once an operation has been executed
in Area B the pointer returns automatically to Area
A.
The pointer operations can also be used before a
program operation, that is the appropriate code
(00h, 01h or 50h) can be issued before the program command 80h is issued (see Figure 12.).

Read Memory Array
Each operation to read the memory area starts
with a pointer operation as shown in the Pointer
Operations section. Once the area (main or spare)
has been selected using the Read A, Read B or
Read C commands four bus cycles (for 512Mb
and 1Gb devices) or three bus cycles (for 128Mb
and 256Mb devices) are required to input the address (refer to Table 6.) of the data to be read.
The device defaults to Read A mode after powerup or a Reset operation.
When reading the spare area addresses:
■
A0 to A3 (x8 devices)
■
A0 to A2 (x16 devices)
are used to set the start address of the spare area
while addresses:
■
A4 to A7 (x8 devices)
■
A3 to A7 (x16 devices)
are ignored.
Once the Read A or Read C commands have
been issued they do not need to be reissued for
subsequent read operations as the pointer remains in the respective area. However, the Read
B command is effective for only one operation,
once an operation has been executed in Area B
the pointer returns automatically to Area A and so
another Read B command is required to start another read operation in Area B.
22/57
Once a read command is issued three types of operations are available: Random Read, Page Read
and Sequential Row Read.
Random Read. Each time the command is issued the first read is Random Read.
Page Read. After the Random Read access the
page data 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 selected column address to last column
address) by pulsing the Read Enable signal.
Sequential Row Read. After the data in last column of the page is output, if the Read Enable signal is pulsed and Chip Enable remains Low then
the next page is automatically loaded into the
Page Buffer and the read operation continues. A
Sequential Row Read operation can only be used
to read within a block. If the block changes a new
read command must be issued.
Refer to Figure 15. and Figure 16. for details of Sequential Row Read operations.
To terminate a Sequential Row Read operation set
the Chip Enable signal to High for more than tEHEL.
Sequential Row Read is not available when the
Chip Enable Don't Care option is enabled.

Page Program
The Page Program operation is the standard operation to program data to the memory array.
The main area of the memory array is programmed by page, however partial page programming is allowed where any number of bytes (1 to
528) or words (1 to 264) can be programmed.
The maximum number of consecutive partial page
program operations allowed in the same page is
three. After exceeding this a Block Erase command must be issued before any further program
operations can take place in that page.
Before starting a Page Program operation a Pointer operation can be performed to point to the area
to be programmed. Refer to the Pointer Operations section and Figure 12. for details.
Each Page Program operation consists of five
steps (see Figure 17.):
1. one bus cycle is required to setup the Page
Program command
2. four bus cycles are then required to input the
program address (refer to Table 6.)
3. the data is then input (up to 528 Bytes/ 264
Words) and loaded into the Page Buffer
4. one bus cycle is required to issue the confirm
command to start the P/E/R Controller.
5. The P/E/R Controller then programs the data
into the array.
Once the program operation has started the Status Register can be read using the Read Status
Register command. During program operations
the Status Register will only flag 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 will be accepted, all other commands will be 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.

Copy Back Program
The Copy Back Program operation is used to copy
the data stored in one page and reprogram it in another page.
The Copy Back Program operation does not require external memory and so the operation is
faster and more efficient because the reading and
loading cycles are not required. The operation is
particularly useful when a portion of a block is updated and the rest of the block needs to be copied
to the newly assigned block.
If the Copy Back Program operation fails an error
is signalled in the Status Register. However as the
standard external ECC cannot be used with the
Copy Back operation bit error due to charge loss
cannot be detected. For this reason it is recommended to limit the number of Copy Back operations on the same data and or to improve the
performance of the ECC.
The Copy Back Program operation requires three
steps:
1. The source page must be read using the Read
A command (one bus write cycle to setup the
command and then 4 bus write cycles to input
the source page address). This operation
copies all 264 Words/ 528 Bytes from the page
into the Page Buffer.
2. When the device returns to the ready state
(Ready/Busy High), the second bus write
cycle of the command is given with the 4 bus
cycles to input the target page address. Refer
to Table 10. for the addresses that must be the
same for the Source and Target pages.
3. Then the confirm command is issued to start
the P/E/R Controller.
After a Copy Back Program operation, a partialpage program is not allowed in the target page until the block has been erased.
See Figure 18. for an example of the Copy Back
operation.

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 19.):
1. One bus cycle is required to setup the Block
Erase command.
2. Only three bus cycles for 512Mb and 1Gb
devices, or two for 128Mb and 256Mb devices
are required to input the block address. The
first cycle (A0 to A7) is not required as only
addresses A14 to A26 (highest address
depends on device density) are valid, A9 to
A13 are ignored. In the last address cycle I/O2
to I/O7 must be set to VIL.
3. One bus cycle is required to issue the confirm
command to start the P/E/R Controller.
Once the erase operation has completed the Status Register can be checked for errors.

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 will be aborted. If it was a program or erase
operation that was aborted, the contents of the
memory locations being modified will no longer be
valid as the data will be partially programmed or
erased.
If the device has already been reset then the new
Reset command will not be 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.
27/57
NAND128-A, NAND256-A, NAND512-A, NAND01G-A
Read Status Register
The device contains a Status Register which 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/O0I/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 or Sequential Row Read operation.
28/57
The Status Register bits are summarized in Table
11., Status Register Bits. Refer to Table 11. in
conjunction with the following text descriptions.
Write Protection Bit (SR7). The Write Protection
bit can be used to 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.
P/E/R Controller Bit (SR6). The Program/Erase/
Read Controller bit 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).
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.
SR5, SR4, SR3, SR2 and SR1 are Reserved.

SOFTWARE ALGORITHMS
This section gives information on the software algorithms that ST recommends to implement 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 a high
voltage. Exposing the device to a 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 14. for value) and it is recommended to implement Garbage
Collection, a Wear-Leveling Algorithm and an Error Correction Code, to extend the number of program and erase cycles and increase the data
retention.
To help integrate a NAND memory into an application ST Microelectronics can provide:
■
File System OS Native reference software,
which supports the basic commands of file
management.
Contact the nearest ST Microelectronics sales office for more details.
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 6th Byte/ 1st Word in the spare area of
the 1st 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 20.
Block Replacement
Over the lifetime of the device additional Bad
Blocks may develop. 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
30/57
attempts to program or erase them will give errors
in the Status Register.
As 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 the “Copy Back Program” section for more details.
Refer to Table 13. for the recommended procedure to follow if an error occurs during an operation.

Garbage Collection
Error Correction Code
When a data page needs to be modified, it is faster
to write to the first available page, and the previous
page is marked 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 21.).
An Error Correction Code (ECC) can be implemented in the Nand Flash memories to identify
and correct errors in the data.
For every 2048 bits in the device it is recommended to implement 22 bits of ECC (16 bits for line parity plus 6 bits for column parity).
An ECC model is available in VHDL or Verilog.
Contact the nearest ST Microelectronics sales office for more details.
Figure 22. Error Detection
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.
Blocks with long-lived data do not endure as many
write cycles as the blocks with frequently-changed
data.
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:
■
First Level Wear-leveling, new data is
programmed to the free blocks that have had
the fewest write cycles
■
Second Level Wear-leveling, long-lived data is
copied to another block so that the original
block can be used for more frequentlychanged 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
Behavioral simulation models. 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
so allow software to be developed before hardware.
IBIS simulations models. IBIS (I/O Buffer Information Specification) models describe the behav-
32/57
ior 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.

APPENDIX A. HARDWARE INTERFACE EXAMPLES
Nand Flash devices can be connected to a microcontroller system bus for code and data storage.
For microcontrollers that have an embedded
NAND controller the NAND Flash can be connected without the addition of glue logic (see
Figure 43.). However a minimum of glue logic is
required for general purpose microcontrollers that
do not have an embedded NAND controller. The
glue logic usually consists of a flip-flop to hold the
Chip Enable, Address Latch Enable and Command Latch Enable signals stable during command and address latch operations, and some
logic gates to simplify the firmware or make the design more robust.
Figure 44. gives an example of how to connect a
NAND Flash to a general purpose microcontroller.
The additional OR gates allow the microcontroller’s Output Enable and Write Enable signals to be
used for other peripherals. The OR gate between
A3 and CSn maps the flip-flop and NAND I/O in
different address spaces inside the same chip select unit, which improves the setup and hold times
and simplifies the firmware. The structure uses the
microcontroller DMA (Direct Memory Access) engines to optimize the transfer between the NAND
Flash and the system RAM.
For any interface with glue logic, the extra delay
caused by the gates and flip-flop must be taken
into account. This delay must be added to the microcontroller’s AC characteristics and register settings to get the NAND Flash setup and hold times.
For mass storage applications (hard disk emulations or systems where a huge amount of storage
is required) NAND Flash memories can be connected together to build storage modules (see Figure 45.).
