TENTATIVE TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS
256-MBIT (32M u 8 BITS) CMOS NAND E2PROM
DESCRIPTION
The device is a 256-Mbit (276,824,064) bit NAND Electrically Erasable and Programmable Read-Only Memory
2
(NAND E PROM) organized as 528 bytes u 32 pages u 2048 blocks. The device uses single power supply (2.7 V to 3.6
V for V
). The device has a 528-byte static register which allows program and read data to be transferred between
CC
the register and the memory cell array in 528-byte increments. The Erase operation is implemented in a single block
unit (16 Kbytes ꢀ 512 bytes: 528 bytes u 32 pages).
The device is a serial-type memory device which utilizes the I/O pins for both address and data input/output as
well as for command inputs. The Erase and Program operations are automatically executed making the device most
suitable for applications such as solid-state file storage, voice recording, image file memory for still cameras and
other systems which require high-density non-volatile memory data storage.

Chip Enable:
CE
The device goes into a low-power Standby mode when
CE goes High during a wait state. The CE signal is ignored when device is in Busy state ( RY/BY L), such
as during a Program or Erase or Read operation, and will not enter Standby mode even if the CE input goes
High.
Write Enable:
WE
The WE signal is used to control the acquisition of data from the I/O port.
Read Enable:
RE
The RE signal controls serial data output. Data is available t
after the falling edge of RE .
REA
The internal column address counter is also incremented (Address ꢁAddress ꢀ l) on this falling edge.
I/O Port: I/O1 to 8
The I/O1 to 8 pins are used as a port for transferring address, command and input/output data to and from the
device.
Write Protect:
WP
The WP signal is used to protect the device from accidental programming or erasing. The internal voltage
regulator is reset when WP is Low. This signal is usually used for protecting the data during the power-on/off
sequence when input signals are invalid.
Ready/Busy:
RY/BY
The RY/BY output signal is used to indicate the operating condition of the device. The RY/BY signal is in
Busy state ( RY/BY L) during the Program, Erase and Read operations and will return to Ready state
( RY/BY H) after completion of the operation. The output buffer for this signal is an open drain.

Operation Mode: Logic and Command Tables
The operation modes such as Program, Erase, Read and Reset are controlled by the ten different command
operations shown in Table 3. Address input, command input and data input/output are controlled by the CLE,
ALE, CE , WE , RE and WP signals, as shown in Table 2.

Start-address input

A data transfer operation from the cell array to the register
starts on the rising edge of WE in the third cycle (after the
address information has been latched). The device will be in
Busy state during this transfer period.
After the transfer period the device returns to Ready state.
Serial data can be output synchronously with the RE clock
from the start pointer designated in the address input cycle.

Read Mode (3)
Read mode (3) has the same timing as Read modes (1) and (2) but is used to access information in the extra
16-byte redundancy area of the page. The start pointer is therefore set to a value between byte 512 and byte 527.

Once a 50H command has been issued, the pointer moves to
the redundant cell locations and only those 16 cells can be
addressed, regardless of the value of the A4-to-A7 address. (An
00H command is necessary to move the pointer back to the
0-to-511 main memory cell location.)

Status Read
The device automatically implements the execution and verification of the Program and Erase operations. The
Status Read function is used to monitor the Ready/Busy status of the device, determine the result (pass/fail) of a
Program or Erase operation, and determine whether the device is in Protect mode. The device status is output
via the I/O port on the RE clock after a 70H command input. The resulting information is outlined in Table 5.

The data is transferred (programmed) from the register to the selected
page on the rising edge of WE following input of the “10H” command.
After programming, the programmed data is transferred back to the
register to be automatically verified by the device. If the programming
does not succeed, the Program/Verify operation is repeated by the device
until success is achieved or until the maximum loop number set in the
device is reached.

Auto Block Erase
The Auto Block Erase operation starts on the rising edge of WE after the Erase Start command “D0H”
which follows the Erase Setup command “60H”. This two-cycle process for Erase operations acts as an ertra layer
of protection from aceidental erasure of data due to external noise. The device automatically executes the Erase

Prohibition of unspecified commands
The operation commands are listed in Table 3. Input of a command other than those specified in Table 3 is
prohibited. Stored data may be corrupted if an unknown command is entered during the command cycle.

(5)
Restriction of command while Busy state
During Busy state, do not input any command except 70H and FFH.
Acceptable commands after Serial Input command “80H”
Once the Serial Input command “80H” has been input, do not input any command other than the Program
Execution command “10H” or the Reset command “FFH”.
If a command other than “10H” or “FFH” is input, the Program operation is not performed.

For this operation the “FFH” command is needed.

The device status can be read out by inputting the Status Read command “70H” in Read mode.
Once the device has been set to Status Read mode by a “70H” command, the device will not return to Read
mode.
Therefore, a Status Read during a Read operation is prohibited.
However, when the Read command “00H” is input during [A], Status mode is reset and the device returns
to Read mode. In this case, data output starts automatically from address N and address input is unnecessary

Note regarding the RE signal
RE The internal column address counter is incremented synchronously with the RE clock in Read mode.
Therefore, once the device has been set to Read mode by a “00H”, “01H” or “50H” command, the internal
column address counter is incremented by the RE clock independently of the address input timing, If the
RE clock input pulses start before the address input, and the pointer reaches the last column address, an
internal read operation (array to register) will occur and the device will enter Busy state. (Refer to Figure 25.)

Invalid blocks (bad blocks)
The device contains unusable blocks. Therefore, at the time of use, please check whether a block is bad and
do not use these bad blocks.
At the time of shipment, all data bytes in a Valid Block are FFH. For Bad
Block, all bytes are not in the FFH state. Please don’t perform erase
operation to Bad Block.
Bad Block
Check if the device has any bad blocks after installation into the system.
Figure 27 shows the test flow for bad block detection. Bad blocks which are
detected by the test flow must be managed as unusable blocks by the
system.
A bad block does not affect the performance of good blocks because it is
isolated from the Bit line by the Select gate

When an error happens in Block A, try to

Do not turn off the power before write/erase operation is complete. Avoid using the device when the
battery is low. Power shortage and/or power failure before write/erase operation is complete will cause loss of data
and/or damage to data.
