The K9F3208W0A is a 4M(4,194,304)x8bit NAND Flash Memory with a spare 128K(131,072)x8bit. Its NAND cell provides
the most cost-effective solution for the solid state mass storage
market. A program operation programs the 528-byte page in
typical 250µs and an erase operation can be performed in typical 2ms on an 8K-byte block.
Data in the page can be read out at 50ns cycle time per byte.
The I/O pins serve as the ports for address and data input/output as well as command inputs. The on-chip write controller
automates all program and erase system functions, including
pulse repetition, where required, and internal verification and
margining of data. Even the write-intensive systems can take
advantage of the K9F3208W0A extended reliability of
1,000,000 program/erase cycles by providing ECC(Error Correction Code) with real time mapping-out algorithm. The
K9F3208W0A is an optimum solution for large nonvolatile storage application such as solid state storage, digital voice
recorder, digital still camera and other portable applications
requiring nonvolatility.

PRODUCT INTRODUCTION
The K9F3208W0A is a 33Mbit(34,603,008 bit) memory organized as 8192 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 the 16
pages formed by one NAND structures, totaling 4,224 NAND structures of 16 cells. 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 block basis. The memory array
consists of 512 separately or grouped erasable 8K-byte blocks. It indicates that the bit by bit erase operation is prohibited on the
K9F3208W0A.
The K9F3208W0A 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. All commands require one bus cycle
except for Block Erase command which requires two cycles : a cycle for erase-setup and another for erase-execution after block
address loading. The 4M byte physical space requires 22 addresses, thereby requiring three 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 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 K9F3208W0A.
Table 1. COMMAND SETS
Function1st. Cycle2nd. CycleAcceptable Command during Busy
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. The 50h command is valid only when the SE(pin 40) is low level.

PIN DESCRIPTION
Command Latch Enable(CLE)
The CLE input controls the path activation 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.
Address Latch Enable(ALE)
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.
Chip Enable(CE)
The CE input is the device selection control. When CE goes high during a read operation the device is returned to standby mode.
However, when the device is in the busy state during program or erase, CE high is ignored, and does not return the device to standby
mode.
Write Enable(WE)
The WE input controls writes to the I/O port. Commands, address and data are latched on the rising edge of the WE pulse.
Read Enable(RE)
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.
Spare Area Enable(SE)
The SE input controls the access of the spare area. When SE is high, the spare area is not accessible for reading or programming.
SE is recommended to be coupled to GND or Vcc and should not be toggled during reading or programming.
I/O Port : I/O 0 ~ I/O 7
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.
Write Protect(WP)
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.
Ready/Busy(R/B)
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.
Power Line(VCC & VCCQ)
The VCCQ is the power supply for I/O interface logic. It is electrically isolated from main power line(VCC=2.7~5.5V) for supporting 5V
tolerant I/O with 5V power supply at VCCQ.

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 or 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 in the spare area. Samsung makes sure that either the 1st or 2nd page of every invalid
block has non-FFh data at the column address of 517. 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 1). Any intentional erasure of the original invalid block information is prohibited.
