BLANK CHECK Operation
ERASE SUSPEND Command
The ERASE SUSPEND (B0h) command temporarily suspends a BLOCK ERASE opera-
tion. One bus WRITE operation is required to issue the command. The block address is
"Don't Care."
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 timeout, the device im-
mediately terminates the timeout period and suspends the ERASE operation. After the
program/erase controller has stopped, the device operates in read mode, and the erase
is suspended.
During an ERASE SUSPEND operation, it is possible to read and execute PROGRAM op-
erations or WRITE TO BUFFER PROGRAM operations in blocks that are not suspended.
Both READ and PROGRAM operations behave normally on these blocks. Reading from
blocks that are suspended will output the status register. If any attempt is made to pro-
gram in a protected block or in the suspended block, the PROGRAM command is ignor-
ed, 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 AUTO SELECT, READ CFI, and UNLOCK BYPASS commands
during an ERASE SUSPEND operation. The READ/RESET command must be issued to
return the device to read array mode before the RESUME command will be accepted.
During an ERASE SUSPEND operation, a bus READ operation to the extended memory
block will output the extended memory block data. After the device enters extended
memory block mode, the EXIT EXTENDED MEMORY BLOCK command must be issued
before the ERASE operation can be resumed.
An ERASE SUSPEND command is ignored if it is written during a CHIP ERASE opera-
tion.
If the ERASE SUSPEND operation is aborted by performing a device reset or power-
down, data integrity cannot be ensured, and it is recommended that the suspended
blocks be erased again.
ERASE RESUME Command
The ERASE RESUME (30h) command restarts the program/erase controller after an
ERASE SUSPEND operation.
The device must be in read array mode before the RESUME command will be accepted.
An erase can be suspended and resumed more than once.
BLANK CHECK Operation
BLANK CHECK Commands
Two commands are required to execute a BLANK CHECK operation: BLANK CHECK
SETUP (EB/76h) and BLANK CHECK CONFIRM AND READ (29h).
The BLANK CHECK operation determines whether a specified block is blank (that is,
completely erased). It can also be used to determine whether a previous ERASE opera-
tion was successful, including ERASE operations that might have been interrupted by
power loss.
