Command interface
4.9
Erase Suspend command
The Erase Suspend Command may be used to temporarily suspend a Block Erase
operation and return the memory to Read mode. The command requires one Bus Write
operation.
The Program/Erase Controller will suspend within 15s of the Erase Suspend Command
being issued. Once the Program/Erase Controller has stopped the memory will be set to
Read mode and the Erase will be suspended. If the Erase Suspend command is issued
during the period when the memory is waiting for an additional block (before the
Program/Erase Controller starts) then the Erase is suspended immediately and will start
immediately when the Erase Resume Command is issued. It will not be possible to select
any further blocks for erasure after the Erase Resume.
During Erase Suspend it is possible to Read and Program cells in blocks that are not being
erased; both Read and Program operations behave as normal on these blocks. Reading
from blocks that are being erased will output the Status Register. It is also possible to enter
the Auto Select mode: the memory will behave as in the Auto Select mode on all blocks until
a Read/Reset command returns the memory to Erase Suspend mode.
4.10
Erase Resume command
The Erase Resume command must be used to restart the Program/Erase Controller from
Erase Suspend. An erase can be suspended and resumed more than once.
