Suspending and Resuming Erase
Because an Erase operation requires on the order of seconds to complete, an Erase Suspend
command is provided. Erase Suspend interrupts an erase sequence to read data from—or program
data to— another block in memory.
After the erase sequence is started, writing the Erase Suspend command to the CUI requests that
the WSM pauses the erase sequence at a predetermined point in the erase algorithm.
The Status Register will indicates if/when the Erase operation has been suspended.
The only valid commands while Erase is suspended are:
During erase-suspend mode, to place the flash memory device in a pseudo-standby mode, set CE#
to V
Erase Resume continues the erase sequence when CE# = V
operation, the Status Register must be read and cleared before the next instruction is issued.
3. When the Status Register indicates that erasure is complete, check the erase-status bit to verify
4. After an Erase operation, clear the Status Register (50H) before attempting the next operation.
5. To prevent inadvertent status- register reads, place the flash memory device in read-array

mode after the erase is complete.
A Read Array/Program command can now be written to the CUI, to read data from/ program
data to blocks other than the one currently suspended.
The Program command can subsequently be suspended to read yet another array location.
