MEMORY MAP
The start address (SA) during read operation is specified divided into three areas using three types of read
commands.
- In read mode (1), start address (SA) is set in area (A).
- In read mode (2), start address (SA) is set in area (B).
- In read mode (3), start address (SA) is set in area (C).
One page consists of a total of 528 bytes broken down into 512 bytes (main memory) and 16 bytes (redundancy).
One block consists of 32 pages.
Caution The data of area (C) is redundancy, which is not programmable and is fixed to all FFH.

Operation Modes
Command input, address input, and serial read are all performed from I/O pins, and the respective statuses are
controlled by the CLE, ALE, WE, RE, and CE signals.

Remarks
1. A0 to A23 are internal addresses.
2. Internal address A8 is set internally with command 00H or 01H.
3. When 50H command is set [read mode (3)], the I/O4, I/O5, I/O6, and I/O7 inputs of the 1st address cycle are VIH
or VIL.

Notes:
1. The data output in read mode (3) is all FFH.
2. The only command that can be executed when the device is Busy is the reset command. Do not set any of the other
commands while the device is Busy.
