GENERAL DESCRIPTION
Offered in 32Mx8bit or 16Mx16bit, the K9F56XXX0B is 256M bit with spare 8M bit capacity. The device is offered in 1.8V or 3.3V
Vcc. Its NAND cell provides the most cost-effective solutIon for the solid state mass storage market. A program operation can be
performed in typical 200µs on the 528-byte(X8 device) or 264-word(X16 device) page and an erase operation can be performed in
typical 2ms on a 16K-byte(X8 device) or 8K-word(X16 device) block. Data in the page can be read out at 50ns cycle time per word.
The I/O pins serve as the ports for address and data input/output as well as command input. The on-chip write control automates all
program and erase functions including pulse repetition, where required, and internal verification and margining of data. Even the
write-intensive systems can take advantage of the K9F56XXX0B′s extended reliability of 100K program/erase cycles by providing
ECC(Error Correcting Code) with real time mapping-out algorithm.
The K9F56XXX0B is an optimum solution for large nonvolatile storage applications such as solid state file storage and other portable
applications requiring non-volatility.

PIN DESCRIPTION
Pin Name
Pin Function
I/O0 ~ I/O7
(K9F5608X0B)
I/O0 ~ I/O15
(K9F5616X0B)
DATA INPUTS/OUTPUTS
The I/O pins are used to input command, address and data, and to output data during read operations. The
I/O pins float to high-z when the chip is deselected or when the outputs are disabled.
I/O8 ~ I/O15 are used only in X16 organization device. Since command input and address input are x8 operation, I/O8 ~ I/O15 are not used to input command & address. I/O8 ~ I/O15 are used only for data input and
output.
CLE
COMMAND LATCH ENABLE
The CLE input controls the activating path for commands sent to the command register. When active high,
commands are latched into the command register through the I/O ports on the rising edge of the WE signal.
ALE
ADDRESS LATCH ENABLE
The ALE input controls the activating path for address to the internal address registers. Addresses are
latched on the rising edge of WE with ALE high.
CE
CHIP ENABLE
The CE input is the device selection control. When the device is in the Busy state, CE high is ignored, and
the device does not return to standby mode in program or erase opertion. Regarding CE control during read
operation, refer to ’Page read’section of Device operation.
RE
READ ENABLE
The RE input is the serial data-out control, and when active drives the data onto the I/O bus. Data is valid
tREA after the falling edge of RE which also increments the internal column address counter by one.
WE
WRITE ENABLE
The WE input controls writes to the I/O port. Commands, address and data are latched on the rising edge of
the WE pulse.
WP
WRITE PROTECT
The WP pin provides inadvertent write/erase protection during power transitions. The internal high voltage
generator is reset when the WP pin is active low.
R/B
READY/BUSY OUTPUT
The R/B output indicates the status of the device operation. When low, it indicates that a program, erase or
random read operation is in process and returns to high state upon completion. It is an open drain output and
does not float to high-z condition when the chip is deselected or when outputs are disabled.
VccQ
OUTPUT BUFFER POWER
VCCQ is the power supply for Output Buffer.
VccQ is internally connected to Vcc, thus should be biased to Vcc.
Vcc
POWER
VCC is the power supply for device.
Vss

N.C
NO CONNECTION
Lead is not internally connected.
GND
GND INPUT FOR ENABLING SPARE AREA
To do sequential read mode including spare area , connect this input pin to Vss or set to static low state
or to do sequential read mode excluding spare area , connect this input pin to Vcc or set to static high state.
DNU
DO NOT USE
Leave it disconnected.
NOTE : Connect all VCC and VSS pins of each device to common power supply outputs.
Do not leave VCC or VSS disconnected.

FLASH MEMORY
PRODUCT INTRODUCTION
The K9F56XXX0B is a 264Mbit(276,824,064 bit) memory organized as 65,536 rows(pages) by 528(X8 device) or 264(X16 device)
columns. Spare eight columns are located from column address of 512~527(X8 device) or 256~263(X16 device). A 528-byte(X8
device) or 264-word(X16 device) data register is connected to memory cell arrays accommodating data transfer between the I/O
buffers and memory during page read and page program operations. The memory array is made up of 16 cells that are serially connected to form a NAND structure. Each of the 16 cells resides in a different page. A block consists of two NAND structures. A NAND
structure consists of 16 cells. Total 16896 NAND cells reside in a block. The array organization is shown in Figure 2-1,2-2. The program and read operations are executed on a page basis, while the erase operation is executed on a block basis. The memory array
consists of 2048 separately erasable 16K-Byte(X8 device) or 8K-Word(X16 device) blocks. It indicates that the bit by bit erase operation is prohibited on the K9F56XXX0B.
The K9F56XXX0B has addresses multiplexed into 8 I/Os(X16 device case: lower 8 I/Os). K9F5616X0B allows sixteen bit wide data
transport into and out of page registers. This scheme dramatically reduces pin counts while providing high performance and allows
systems upgrades to future densities by maintaining consistency in system board design. Command, address and data are all written
through I/O′s by bringing WE to low while CE is low. Data is latched on the rising edge of WE. Command Latch Enable(CLE) and
Address Latch Enable(ALE) are used to multiplex command and address respectively, via the I/O pins. Some commands require one
bus cycle. For example, Reset command, Read command, Status Read command, etc require just one cycle bus. Some other commands like Page Program and Copy-back Program and Block Erase, require two cycles: one cycle for setup and the other cycle for
execution. The 32M-byte(X8 device) or 16M-word(X16 device) physical space requires 24 addresses, thereby requiring three cycles
for word-level addressing: column address, low row address and high row address, in that order. Page Read and Page Program
need the same three address cycles following the required command input. In Block Erase operation, however, only the two row
address cycles are used. Device operations are selected by writing specific commands into the command register. Table 1 defines
the specific commands of the K9F56XXX0B.
The device includes one block sized OTP(One Time Programmable), which can be used to increase system security or to provide
identification capabilities. Detailed information can be obtained by contact with Samsung.

NAND Flash Technical Notes
Invalid Block(s)
Invalid blocks are defined as blocks that contain one or more invalid bits whose reliability is not guaranteed by Samsung. The information regarding the invalid block(s) is so called as the invalid block information. Devices with invalid block(s) have the same quality
level as devices with all valid blocks and have the same AC and DC characteristics. An invalid block(s) does not affect the performance of valid block(s) because it is isolated from the bit line and the common source line by a select transistor. The system design
must be able to mask out the invalid block(s) via address mapping. The 1st block, which is placed on 00h block address, is fully guaranteed to be a valid block, does not require Error Correction.
Identifying Invalid Block(s)
All device locations are erased(FFh) except locations where the invalid block(s) information is written prior to shipping. The invalid
block(s) status is defined by the 6th byte(X8 device) or 1st word(X16 device) in the spare area. Samsung makes sure that either the
1st or 2nd page of every invalid block has non-FFh(X8 device) or non-FFFFh(X16 device) data at the column address of 517(X8
device) or 256 and 261(X16 device). Since the invalid block information is also erasable in most cases, it is impossible to recover the
information once it has been erased. Therefore, the system must be able to recognize the invalid block(s) based on the original
invalid block information and create the invalid block table via the following suggested flow chart(Figure 3). Any intentional erasure of
the original invalid block information is prohibited.

NAND Flash Technical Notes (Continued)
Error in write or read operation
Within its life time, the additional invalid blocks may develop with NAND Flash memory. Refer to the qualification report for the actual
data.The following possible failure modes should be considered to implement a highly reliable system. In the case of status read failure after erase or program, block replacement should be done. Because program status fail during a page program does not affect
the data of the other pages in the same block, block replacement can be executed with a page-sized buffer by finding an erased
empty block and reprogramming the current target data and copying the rest of the replaced block. To improve the efficiency of
memory space, it is recommended that the read or verification failure due to single bit error be reclaimed by ECC without any block
replacement. The said additional block failure rate does not include those reclaimed blocks.

FLASH MEMORY
Pointer Operation of K9F5608X0B(X8)
Samsung NAND Flash has three address pointer commands as a substitute for the two most significant column addresses. ’00h’
command sets the pointer to ’A’area(0~255byte), ’01h’command sets the pointer to ’B’area(256~511byte), and ’50h’command sets
the pointer to ’C’ area(512~527byte). With these commands, the starting column address can be set to any of a whole
page(0~527byte). ’00h’ or ’50h’ is sustained until another address pointer command is inputted. ’01h’ command, however, is effective only for one operation. After any operation of Read, Program, Erase, Reset, Power_Up is executed once with ’01h’ command,
the address pointer returns to ’A’area by itself. To program data starting from ’A’or ’C’area, ’00h’or ’50h’command must be inputted before ’80h’ command is written. A complete read operation prior to ’80h’ command is not necessary. To program data starting
from ’B’area, ’01h’command must be inputted right before ’80h’command is written.

Pointer Operation of K9F5616X0B(X16)
Samsung NAND Flash has two address pointer commands as a substitute for the most significant column address. ’00h’command
sets the pointer to ’A’ area(0~255word), and ’50h’ command sets the pointer to ’B’ area(256~263word). With these commands, the
starting column address can be set to any of a whole page(0~263word). ’00h’or ’50h’is sustained until another address pointer command is inputted. To program data starting from ’A’ or ’B’ area, ’00h’ or ’50h’ command must be inputted before ’80h’ command is
written. A complete read operation prior to ’80h’command is not necessary.

System Interface Using CE don’t-care.
For an easier system interface, CE may be inactive during the data-loading or sequential data-reading as shown below. The internal
528byte/264word page registers are utilized as seperate buffers for this operation and the system design gets more flexible. In addition, for voice or audio applications which use slow cycle time on the order of u-seconds, de-activating CE during the data-loading
and reading would provide significant savings in power consumption.

DEVICE OPERATION
PAGE READ
Upon initial device power up, the device defaults to Read1 mode. This operation is also initiated by writing 00h to the command register along with three address cycles. Once the command is latched, it does not need to be written for the following page read operation. Two types of operations are available : random read, serial page read.
The random read mode is enabled when the page address is changed. The 528 bytes(X8 device) or 264 words(X16 device) of data
within the selected page are transferred to the data registers in less than 10µs(tR). The system controller can detect the completion of
this data transfer(tR) by analyzing the output of R/B pin. Once the data in a page is loaded into the registers, they may be read out in
50ns cycle time by sequentially pulsing RE. High to low transitions of the RE clock output the data starting from the selected column
address up to the last column address[column 511/ 527(X8 device) 255 /263(X16 device) depending on the state of GND input pin].
The way the Read1 and Read2 commands work is like a pointer set to either the main area or the spare area. The spare area of 512
~527 bytes(X8 device) or 256~263 words(X16 device) may be selectively accessed by writing the Read2 command with GND input
pin low. Addresses A0~A3(X8 device) or A0~A2(X16 device) set the starting address of the spare area while addresses A4~A7 are
ignored in X8 device case or A3~A7 must be "L" in X16 device case. The Read1 command is needed to move the pointer back to the
main area. Figures 8, 9 show typical sequence and timings for each read operation.
Sequential Row Read is available only for K9F5608U0B_Y,P and K9F5608U0B_V,F :
After the data of last column address is clocked out, the next page is automatically selected for sequential row read. Waiting 10µs
again allows reading the selected page. The sequential row read operation is terminated by bringing CE high. Unless the operation
is aborted, the page address is automatically incremented for sequential row read as in Read1 operation and spare sixteen bytes of
each page may be sequentially read. The Sequential Read 1 and 2 operation is allowed only within a block and after the last page of
a block is readout, the sequential read operation must be terminated by bringing CE high. When the page address moves onto the
next block, read command and address must be given. Figures 8-1, 9-1 show typical sequence and timings for sequential row read
operation.

PAGE PROGRAM
The device is programmed basically on a page basis, but it does allow multiple partial page programing of a byte/word or consecutive
bytes/words up to 528(X8 device) or 264(X16 device), in a single page program cycle. The number of consecutive partial page programming operation within the same page without an intervening erase operation should not exceed 2 for main array and 3 for spare
array. The addressing may be done in any random order in a block. A page program cycle consists of a serial data loading period in
which up to 528 bytes(X8 device) or 264 words(X16 device) of data may be loaded into the page register, followed by a non-volatile programming period where the loaded data is programmed into the appropriate cell. About the pointer operation, please refer to the
attached technical notes.
The serial data loading period begins by inputting the Serial Data Input command(80h), followed by the three address cycles input
and then serial data loading. The words other than those to be programmed do not need to be loaded.The Page Program confirm
command(10h) initiates the programming process. Writing 10h alone without previously entering the serial data will not initiate the
programming process. The internal write controller automatically executes the algorithms and timings necessary for program and
verify, thereby freeing the system controller for other tasks. Once the program process starts, the Read Status Register command
may be entered, with RE and CE low, to read the status register. The system controller can detect the completion of a program cycle
by monitoring the R/B output, or the Status bit(I/O 6) of the Status Register. Only the Read Status command and Reset command
are valid while programming is in progress. When the Page Program is complete, the Write Status Bit(I/O 0) may be checked(Figure
10). The internal write verify detects only errors for "1"s that are not successfully programmed to "0"s. The command register remains
in Read Status command mode until another valid command is written to the command register.

COPY-BACK PROGRAM
The copy-back program is configured to quickly and efficiently rewrite data stored in one page within the array to another page within
the same array without utilizing an external memory. Since the time-consuming sequently-reading and its re-loading cycles are
removed, the system performance is improved. The benefit is especially obvious when a portion of a block is updated and the rest of
the block also need to be copied to the newly assigned free block. The operation for performing a copy-back is a sequential execution of page-read without burst-reading cycle and copying-program with the address of destination page. A normal read operation
with "00h" command with the address of the source page moves the whole 528bytes/264words(X8 device:528bytes, X16
device:264words) data into the internal buffer. As soon as the Flash returns to Ready state, copy-back programming command "8Ah"
may be given with three address cycles of target page followed. The data stored in the internal buffer is then programmed directly
into the memory cells of the destination page. Once the Copy-Back Program is finished, any additional partial page programming into
the copied pages is prohibited before erase. Since the memory array is internally partitioned into two different planes, copy-back program is allowed only within the same memory plane. Thus, A14, the plane address, of source and destination page address must be
the same. "When there is a program-failure at Copy-Back operation, error is reported by pass/fail status. But, if Copy-Back
operations are accumulated over time, bit error due to charge loss is not checked by external error detection/correction
scheme. For this reason, two bit error correction is recommended for the use of Copy-Back operation."

BLOCK ERASE
The Erase operation is done on a block basis. Block address loading is accomplished in two cycles initiated by an Erase Setup command(60h). Only address A14 to A24 is valid while A9 to A13 is ignored. The Erase Confirm command(D0h) following the block
address loading initiates the internal erasing process. This two-step sequence of setup followed by execution command ensures that
memory contents are not accidentally erased due to external noise conditions.
At the rising edge of WE after the erase confirm command input, the internal write controller handles erase and erase-verify. When
the erase operation is completed, the Write Status Bit(I/O 0) may be checked. Figure 12 details the sequence.

READ STATUS
The device contains a Status Register which may be read to find out whether program or erase operation is completed, and whether
the program or erase operation is completed successfully. After writing 70h command to the command register, a read cycle outputs
the content of the Status Register to the I/O pins on the falling edge of CE or RE, whichever occurs last. This two line control allows
the system to poll the progress of each device in multiple memory connections even when R/B pins are common-wired. RE or CE
does not need to be toggled for updated status. Refer to table 4 for specific Status Register definitions. The command register
remains in Status Read mode until further commands are issued to it. Therefore, if the status register is read during a random read
cycle, a read command(00h or 50h) should be given before sequential page read cycle.

READ ID
The device contains a product identification mode, initiated by writing 90h to the command register, followed by an address input of
00h. Two read cycles sequentially output the manufacture code(ECh), and the device code respectively. The command register
remains in Read ID mode until further commands are issued to it. Figure 13 shows the operation sequence.

RESET
The device offers a reset feature, executed by writing FFh to the command register. When the device is in Busy state during random
read, program or erase mode, the reset operation will abort these operations. The contents of memory cells being altered are no
longer valid, as the data will be partially programmed or erased. The command register is cleared to wait for the next command, and
the Status Register is cleared to value C0h when WP is high. Refer to table 5 for device status after reset operation. If the device is
already in reset state a new reset command will not be accepted by the command register. The R/B pin transitions to low for tRST
after the Reset command is written. Refer to Figure 14 below.

READY/BUSY
The device has a R/B output that provides a hardware method of indicating the completion of a page program, erase and random
read completion. The R/B pin is normally high but transitions to low after program or erase command is written to the command register or random read is started after address loading. It returns to high when the internal controller has finished the operation. The pin
is an open-drain driver thereby allowing two or more R/B outputs to be Or-tied. Because pull-up resistor value is related to tr(R/B)
and current drain during busy(ibusy) , an appropriate value can be obtained with the following reference chart(Fig 15). Its value can
be determined by the following guidance.

Data Protection & Powerup sequence
The device is designed to offer protection from any involuntary program/erase during power-transitions. An internal voltage detector
disables all functions whenever Vcc is below about 1.3V. WP pin provides hardware protection and is recommended to be kept at
VIL during power-up and power-down and recovery time of minimum 10µs is required before internal circuit gets ready for any command sequences as shown in Figure 16. The two step command sequence for program/erase provides additional software protection.
