PIN CONFIGURATION

The K9F8008W0M is a 1M(1,048,576)x8bit NAND Flash Mem­ory with a spare 32K(32,768)x8bit. Its NAND cell provides the
most cost-effective solution for the solid state mass storage
market. A program operation programs the 264-byte page in
typically 250µs and an erase operation can be performed in
typically 2ms on a 4K-byte block.
Data in the page can be read out at 80ns 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 verify and margin­ing of data. Even the write-intensive systems can take advan­tage of the K9F8008W0M extended reliability of 1,000,000
program/erase cycles by providing either ECC(Error Correction
Code) or real time mapping-out algorithm. These algorithms
have been implemented in many mass storage applications
and also the spare 8bytes of a page combined with the other
256 bytes can be utilized by system-level ECC.
The K9F8008W0M 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 K9F8008W0M is an 8.6Mbit(8,650,752 bit) memory organized as 4096 rows by 264 columns. Spare eight columns are located
from column address of 256 to 263. A 264-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 2,112 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 256 separately or grouped erasable 4K-byte blocks. It indicates that the bit by bit erase operation is prohibited on the
K9F8008W0M.

The K9F8008W0M 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 2M byte physical space requires 21 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 K9F8008W0M.

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 path activation for address and input data to the internal address/data register.
Addresses are latched on the rising edge of WE with ALE high, and input data is latched when ALE is low.

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 devices 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.

I/O Port : I/O0 ~ I/O7

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.

Parameter Symbol Rating Unit

Voltage on any pin relative to VSS VIN -0.6 to +7.0 V

Temperature Under Bias

Storage Temperature TSTG -65 to +150 °C
Short Circuit Output Current IOS 5 mA

NOTE :

1. Minimum DC voltage is -0.3V on input/output pins. During transitions, this level may undershoot to -2.0V for periods <30ns.
Maximum DC voltage on input/output pins is VCC+0.3V which, during transitions, may overshoot to VCC+2.0V for periods <20ns.

2. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. Functional operation should be restricted to the conditions
as detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
