NOTE :
The Erase operation is done on a block basis. Block address loading is accomplished in two cycles initiated by an Erase Setup com-
mand(60h). Only address A
Confirm command(D0h) following the block address loading initiates the internal erasing process. This two-step sequence of setup
followed by execution command ensures that memory contents are not accidentally erased due to external noise conditions.
At the rising edge of WE after the erase confirm command input, the internal write controller handles erase and erase-verify. When
the erase operation is completed, the Write Status Bit(I/O 0) may be checked. Figure 13 details the sequence.
Figure 13. Block Erase Operation
READ STATUS
The device contains a Status Register which may be read to find out whether program or erase operation is completed, and whether
the program or erase operation is completed successfully. After writing 70h command to the command register, a read cycle outputs
the content of the Status Register to the I/O pins on the falling edge of CE or RE, whichever occurs last. This two line control allows
the system to poll the progress of each device in multiple memory connections even when R/B pins are common-wired. RE or CE
does not need to be toggled for updated status. Refer to table 2 for specific Status Register definitions. The command register
remains in Status Read mode until further commands are issued to it. Therefore, if the status register is read during a random read
cycle, the read command(00h) should be given before starting read cycles.

1. True Ready/Busy represents internal program operation status which is being executed in cache program mode.
2. I/Os defined ’ Not use’ are recommended to be masked out when Read Status is being executed.
