Mode Description

Read

Serial Read (1): Memory data D0 to D2111 in the sector of address SA is sequentially read. Output data is

not valid after the number of the SC pulse exceeds 2112. When CA is input, memory data D (m) to 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 to m). The mode turns back to the standby mode at any time when CE is VIH.

Serial Read (2): Memory data D2048 to 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 CE is VIH.

Automatic Erase

Single Sector Erase: Memory data D0 to 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

RDY/Busy 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 to D2111 must be read and kept outside of the sector before the

sector erase.

Automatic Program

Program (1): Program data PD0 to PD2111 is programmed into the sector of address SA automatically by

internal control circuits. When CA is input, program data PD (m) to PD (m + j) is programmed from CA into

the sector of address SA automatically by internal control circuits. By using program (1), data can

additionally be programed 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 RDY/Busy 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 to PD2111.

Program (2): Program data PD0 to 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

RDY/Busy 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 to PD2111.

Program (3): Program data PD2048 to PD2111 is programmed into the sector of address SA automatically

by internal control circuits. By using program (3), data can additionally be programed for each sector befor

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 RDY/Busy signal and status data

polling. Programmed bits in the sector turn from "1" to "0" when they are programmed.
