Extended Memory Block command must be issued before the erase operation can be
resumed.
The Erase Suspend command is ignored if written during Chip Erase operations.
Refer to
out and Block Erase Suspend latency time.
If the Erase Suspend operation is aborted by performing a reset or powering down the
device, data integrity cannot be ensured, and it is recommended to erase again the blocks
suspended.
Erase Resume command
The Erase Resume command is used to restart the Program/Erase controller after an Erase
Suspend.
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.
Program Suspend command
The Program Suspend command allows the system to interrupt a program operation so that
data can be read from any block. When the Program Suspend command is issued during a
program operation, the device suspends the program operation within the Program
Suspend latency time (see
the Status Register bits.
After the program operation has been suspended, the system can read array data from any
address. However, data read from program-suspended addresses is not valid.
The Program Suspend command may also be issued during a program operation while an
erase is suspended. In this case, data may be read from any addresses not in Erase
Suspend or Program Suspend. If a read is needed from the Extended Memory Block area
(one-time program area), the user must use the proper command sequences to enter and
exit this region.
The system may also issue the Auto Select command sequence when the device is in the
Program Suspend mode. The system can read as many Auto Select codes as required.
When the device exits the Auto Select mode, the device reverts to the Program Suspend
mode, and is ready for another valid operation. See Auto Select command sequence for
more information.
If the Program Suspend operation is aborted by performing a reset or powering down the
device, data integrity cannot be ensured, and it is recommended to program again the
words or bytes aborted.
Program Resume command
After the Program Resume command is issued, the device reverts to programming. The
controller can determine the status of the program operation using the DQ7 or DQ6 status
bits, just as in the standard program operation. Refer to
Program waveforms (8-bit mode)
waveforms (16-bit mode)
The system must issue a Program Resume command, to exit the Program Suspend mode
and to continue the programming operation.
