any more blocks. Each additional block must therefore be selected within the time-out
period of the last block. The time-out timer restarts when an additional block is selected.
After the sixth Bus Write operation, a Bus Read operation outputs the Status Register. See

Program/Erase controller has started the Block Erase operation.
After the Block Erase operation has completed, the memory returns to the Read mode,
unless an error has occurred. When an error occurs, Bus Read operations will continue to
output the Status Register. A Read/Reset command must be issued to reset the error
condition and return to Read mode.
If any selected blocks are protected then these are ignored and all the other selected blocks
are erased. If all of the selected blocks are protected the Block Erase operation appears to
start but will terminate within about 100 µs, leaving the data unchanged. No error condition
is given when protected blocks are ignored.
During the Block Erase operation the memory ignores all commands except the Erase
Suspend command and the Read/Reset command which is only accepted during the time-
out period. Typical Block Erase time and Block Erase time-out are given in
The Block Erase operation is aborted by performing a reset or powering down the device. In
this case, data integrity cannot be ensured, and it is recommended to erase again the
blocks aborted.
Erase Suspend command
The Erase Suspend command can be used to temporarily suspend a Block Erase
operation. One Bus Write operation is required to issue the command together with the
block address.
After the command sequence is written, a minimum Block Erase time-out occurs (see
Table
commands can be written.
The Program/Erase controller suspends the erase operation within the Erase Suspend
Latency time of the Erase Suspend command being issued. However, when the Erase
Suspend command is written during the Block Erase time-out, the device immediately
terminates the time-out period and suspends the erase operation.
Once the Program/Erase controller has stopped, the memory operates in Read mode and
the Erase is suspended.
During Erase Suspend it is possible to read and execute Program or Write to Buffer
Program operations in blocks that are not suspended; both read and program operations
behave as normal on these blocks. Reading from blocks that are suspended will output the
Status Register. If any attempt is made to program in a protected block or in the suspended
block then the Program command is ignored and the data remains unchanged. In this case
the Status Register is not read and no error condition is given.
It is also possible to issue the Auto Select, Read CFI Query and Unlock Bypass commands
during an Erase Suspend. The Read/Reset command must be issued to return the device to
Read Array mode before the Resume command will be accepted.
During Erase Suspend a Bus Read operation to the Extended Memory Block will output the
Extended Memory Block data. Once in the Extended Memory Block mode, the Exit
