Suspending and Resuming Programming
The Program Suspend command halts the in-progress program operation to read data from another
flash memory location.

Erase Mode
To erase a block:
1. After the programming process starts, writing the Program Suspend command to the CUI
2. The flash memory device continues to output Status Register data after the Program Suspend
3. Polling SR.7 and SR.2 determines when the program operation has been suspended (both are
4. A Read Array command can now be written to the CUI to read data from blocks other than the

This address is latched internally when the Erase Confirm command is issued.
Block erasure sets all bits within the block to 1. Only one block can be erased at a time.
While the erase executes, status bit 7 is 0.
