CMOS 3.3V-ONLY SERIAL READ FLASH MEMORY

Mode Description

Read

Serial read(1)

Memory data D0-D2111 in the sector of address SA is sequentially read. Output data is not valid after the number of the

serial clock SC pulse exceeds 2112. When the column address CA is input after SA, memory data D(m) -D(m+j) in the sector

of address SA is sequentially read. Then output data is not valid after the number of the SC pulse exceeds (2112-m).

The mode turns back to the Standby mode at any time when is VIH.

Serial read(2)

Memory data D2048-D2111 in the sector of address SA is sequentially read. Output data is not valid after the number of the

SC pulse exceeds 64.The mode turns back to the Standby mode at any time when is VIH.

Automatic Erase

Single sector Erase

Memory data D0-D2111 in the sector of address SA is erased automatically by internal control circuits. After the sector

erase starts, the erasure completion can be checked through the R/ signal and status data polling. All the bits in the sector

are “1” after the erase. The sector valid data stored in a part of memory data D2048-D2111 must be read and kept outside of

the sector before the sector erase.

Automatic program

Program(1)

Program data PD0-PD2111 is programmed into the sector of address SA automatically by internal control circuits. When

CA is input after SA, program data PD(m) -PD(m+j) is programmed form CA into the sector of address SA automatically by

internal control circuits. By using program(1), data can additionally be programmed for each sector before the following erase.

When the column is programmed, the data of the column must be [FF].

After the programming starts, the program completion can be checked through the R/ signal and status data polling.

Programmed bits in the sector turn from “1” to “0” when they are programmed. The sector valid data should be included in the

program data PD2048-PD2111. In this mode, E/W number of times must be counted whenever program(1) execute.

Program(2)

Program data PD0-PD2111 is programmed into the sector of address SA automatically by internal control circuits. After the

programming starts, the program completion can be checked through the R/ signal and status data polling. Programmed bits

in the sector turn from “1” to “0” when they are programmed. The sector must be erased before programming. The sector valid

data should be included in the program data PD2048-PD2111. In this mode, Write number of times must be counted whenever

program(2) execute.

Program(3)

Program data PD2048-PD2111 is programmed into the sector of address SA automatically by internal control circuits. By

using program(3), data can additionally be programmed for each sector before the following erase. When the column is

programmed, the data of the column must be [FF].

After the programming starts, the program completion can be checked through the R/ signal and status data polling.

Programmed bits in the sector turn from “1” to “0” when they programmed. In this mode, E/W number of times must be counted

whenever program(3) execute.

Program(4)

Program data PD0-PD2111 is programmed into the sector of address SA automatically by internal control circuits. When CA

is input after SA, program data PD(m) -PD(m+j) is programmed from CA into the sector of address SA automatically by internal

control circuits. By using program(4), data can be rewritten for each sector before the following erase. So the column data

before programming operation are either “1” to “0”.

After the programming starts,the program completion can be checked through the R/ single and status data polling. The

sector valid data should be included in the program data PD2048-PD2111. In this mode, E/W number of times must be counted

whenever program(4) execute.
