GENERAL DESCRIPTION
Offered in 64Mx8bit or 32Mx16bit, the K9F12XXX0A is 512M bit with spare 16M 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 K9F12XXX0A′s extended reliability of 100K program/erase cycles by providing
ECC(Error Correcting Code) with real time mapping-out algorithm.
The K9F12XXX0A is an optimum solution for large nonvolatile storage applications such as solid state file storage and other portable
applications requiring non-volatility.

Pin Function
I/O0 ~ I/O7
(K9F1208X0A)
I/O0 ~ I/O15
(K9F1216X0A)
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

NO CONNECTION
Lead is not internally connected.

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 K9F1208X0A is a 528Mbit(553,648,218 bit) memory organized as 131,072 rows(pages) by 528 columns. Spare sixteen columns
are located from column address of 512 to 527. A 528-byte 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. 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 4,096 separately erasable 16K-byte blocks. It indicates that the bit by bit erase operation is prohibited
on the K9F1208X0A.
The K9F1208X0A has addresses multiplexed into 8 I/O's. This scheme dramatically reduces pin counts 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. The 64M byte physical space requires 26
addresses, thereby requiring four cycles for byte-level addressing: column address, low row address and high row address, in that
order. Page Read and Page Program need the same four address cycles following the required command input. In Block Erase operation, however, only the three 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 K9F1208X0A.
The device provides simultaneous program/erase capability up to four pages/blocks. By dividing the memory array into four 128Mbit
separate planes, simultaneous multi-plane operation dramatically increases program/erase performance by 4X while still maintaining
the conventional 512 byte(X8 device) or 256 word(X16 device) structure.
The extended pass/fail status for multi-plane program/erase allows system software to quickly identify the failing page/block out of
selected multiple pages/blocks. Usage of multi-plane operations will be described further throughout this document.
In addition to the enhanced architecture and interface, the device incorporates copy-back program feature from one page to another
of the same plane without the need for transporting the data to and from the external buffer memory. Since the time-consuming burstreading and data-input cycles are removed, system performance for solid-state disk application is significantly increased.
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.

NOTE : 1. The 00h command defines starting address of the 1st half of registers.
The 01h command defines starting address of the 2nd half of registers.
After data access on the 2nd half of register by the 01h command, the status pointer is
automatically moved to the 1st half register(00h) on the next cycle.
2. Page Program(True) and Copy-Back Program(True) are available on 1 plane operation.
Page Program(Dummy) and Copy-Back Program(Dummy) are available on the 2nd,3rd,4th plane of multi plane operation.
3. The 71h command should be used for read status of Multi Plane operation.
Caution : Any undefined command inputs are prohibited except for above command set of Table 1.

Memory Map
The device is arranged in four 128Mbit memory planes. Each plane contains 1,024 blocks and 528 byte(X8 device) or 264 word(X16
device) page registers. This allows it to perform simultaneous page program and block erase by selecting one page or block from
each plane. The block address map is configured so that multi-plane program/erase operations can be executed for every four
sequential blocks.

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 4). 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 K9F1208X0A(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 K9F1216X0A(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.

FLASH MEMORY
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 1264word page registers are utilized as separate 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 four address cycles. Once the command is latched, it does not need to be written for the following page read operation.
Three types of operations are available : random read, serial page read and sequential row read.
The random read mode is enabled when the page address is changed. The 528 bytes(x8 device) or 264words(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. CE must be held low while in busy for K9F12XXU0A-YXB0 or K9F1208U0AVXB0, while CE is don’t-care with K9F12XXX0A-DXB0. If CE goes high before the device returns to Ready, the random read operation is interrupted and Busy returns to Ready as the defined by tCRY. Since the operation was aborted, the serial page read does not
output valid data. 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 stating from the selected column address up to the last column address.
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
to 527 bytes (x8 device) or 256 to 263 words(x16 device)may be selectively accessed by writing the Read2 command. Addresses A0
to A3 set the starting address of the spare area while addresses A4 to A7 are ignored. The Read1 command(00h/01h) is needed to
move the pointer back to the main area. Figures 7 to 10 show typical sequence and timings for each read operation.
Sequential Row Read is available only on K9F12XXX0A-Y,P or K9F1208U0A-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 9, 10 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 or consecutive bytes
up to 528 bytes(x8 device) or 264words(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 must not exceed 1 for main array and 2 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 264words(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. Serial data loading can be started from 2nd half
array by moving pointer. 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 four cycle address input and
then serial data loading. The bytes 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 state control 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 11).
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.

BLOCK ERASE
The Erase operation is done on a block(16K Byte) basis. Block address loading is accomplished in three cycles initiated by an Erase
Setup command(60h). Only address A14 to A25 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.

Multi-Plane Page Program
Multi-Plane Page Program is an extension of Page Program, which is executed for a single plane with 528 byte page registers. Since
the device is equipped with four memory planes, activating the four sets of 528 byte page registers enables a simultaneous programming of four pages. Partial activation of four planes is also permitted.
After writing the first set of data up to 528 byte into the selected page register, Dummy Page Program command (11h) instead of
actual Page Program (10h) is inputted to finish data-loading of the current plane and move to the next plane. Since no programming
process is involved, R/B remains in Busy state for a short period of time(tDBSY). Read Status command (standard 70h or alternate
71h) may be issued to find out when the device returns to Ready state by polling the Ready/Busy status bit(I/O 6). Then the next set
of data for one of the other planes is inputted with the same command and address sequences. After inputting data for the last plane,
actual True Page Program (10h) instead of dumy Page Program command (11h) must be followed to start the programming process.
The operation of R/B and Read Status is the same as that of Page Program. Since maximum four pages are programmed simultaneously, pass/fail status is available for each page when the program operation completes. The extended status bits (I/O1 through I/
O 4) are checked by inputting the Read Multi-Plane Status Register. Status bit of I/O 0 is set to "1" when any of the pages fails.
Multi-Plane page Program with "01h" pointer is not supported, thus prohibited.

Restriction in addressing with Multi Plane Page Program
While any block in each plane may be addressable for Multi-Plane Page Program, the five least significant addresses(A9-A13) for
the selected pages at one operation must be the same. Figure 14 shows an example where 2nd page of each addressed block is
selected for four planes. However, any arbitrary sequence is allowed in addressing multiple planes as shown in Figure15.

Multi-Plane Block Erase
Basic concept of Multi-Plane Block Erase operation is identical to that of Multi-Plane Page Program. Up to four blocks, one from each
plane can be simultaneously erased. Standard Block Erase command sequences (Block Erase Setup command followed by three
address cycles) may be repeated up to four times for erasing up to four blocks. Only one block should be selected from each plane.
The Erase Confirm command initiates the actual erasing process. The completion is detected by analyzing R/B pin or Ready/Busy
status (I/O 6). Upon the erase completion, pass/fail status of each block is examined by reading extended pass/fail status(I/O 1
through I/O 4).

FLASH MEMORY
Copy-Back Program
The copy-back program is configured to quickly and efficiently rewrite data stored in one page within the plane to another page within
the same plane 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 program 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 and the address of the source page moves the whole 528byte data into the internal page registers. As soon
as the device returns to Ready state, Page-Copy Data-input command (8Ah) with the address cycles of destination page followed
may be written. The Program Confirm command (10h) is required to actually begin the programming operation. Copy-Back Program
operation is allowed only within the same memory plane. Once the Copy-Back Program is finished, any additional partial page programming into the copied pages is prohibited before erase. A14 and A15 must be the same between source and target page.
Figure18 shows the command sequence for single plane operation. "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."

FLASH MEMORY
Multi-Plane Copy-Back Program
Multi-Plane Copy-Back Program is an extension of one page Copy-Back Program into four plane operation. Since the device is
equipped with four memory planes, activating the four sets of 528 bytes(x8 device) or 264words(x16 device)page registers enables a
simultaneous Multi-Plane Copy-Back programming of four pages. Partial activation of four planes is also permitted.
First, normal read operation with the "00h"command and address of the source page moves the whole 528 byte data into internal
page buffers. Any further read operation for transferring the addressed pages to the corresponding page register must be executed
with "03h" command instead of "00h" command. Any plane may be selected without regard to "00h" or "03h". Up to four planes may
be addressed. Data moved into the internal page registers are loaded into the destination plane addresses. After the input of command sequences for reading the source pages, the same procedure as Multi-Plane Page programming except for a replacement
address command with "8Ah" is executed. Since no programming process is involved during data loading at the destination plane
address , R/B remains in Busy state for a short period of time(tDBSY). Read Status command (standard 70h or alternate 71h) may
be issued to find out when the device returns to Ready state by polling the Ready/Busy status bit(I/O 6). After inputting data for the
last plane, actual True Page Program (10h) instead of dummy Page Program command (11h) must be followed to start the programming process. The operation of R/B and Read Status is the same as that of Page Program. Since maximum four pages are programmed simultaneously, pass/fail status is available for each page when the program operation completes. No pointer operation is
supported with Multi-Plane Copy-Back Program. Once the Multi-Plane Copy-Back Program is finished, any additional partial
page programming into the copied pages is prohibited before erase once the Multi-Plane Copy-Back Program is finished.

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.
For Read Status of Multi Plane Program/Erase, the Read Multi-Plane Status command(71h) should be used to find out whether
multi-plane program or erase operation is completed, and whether the program or erase operation is completed successfully. The
pass/fail status data must be checked only in the Ready condition after the completion of Multi-Plane program or erase operation.

Read ID
The device contains a product identification mode, initiated by writing 90h to the command register, followed by an address input of
00h. Four read cycles sequentially output the manufacture code(ECh), and the device code (76h), Reserved(A5h), Multi plane operation code(C0h) respectively. A5h must be don’t-cared. C0h means that device supports Multi Plane operation. The command register remains in Read ID mode until further commands are issued to it. Figure 21 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 22 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 23). Its value can be
determined by the following guidance.

Data Protection & Power-up 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 1.1V(1.8V device) or 2V(3.3V device). WP pin provides hardware protection and
is recommended to be kept at V IL during power-up and power-down. A recovery time of minimum 10µs is required before internal circuit gets ready for any command sequences as shown in Figure 24. The two step command sequence for program/erase provides
additional software protection.
