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 Block will output the
Extended Block data. Once in the Extended Block mode, the Exit Extended Block command
must be issued before the erase operation can be resumed.
Erase Resume command
The Erase Resume command is used to restart the Program/Erase Controller after an
Erase Suspend. The command must include the Bank Address of the Erase-Suspended
Bank, otherwise the Program/Erase Controller is not restarted.
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
Addresses of the Block being programmed must be specified in the Program Suspend
command.
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 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.
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. See Write Operation Status for more
information.
The system must write the Program Resume command, specifying the Bank addresses of
the Program-Suspended Block, to exit the Program Suspend mode and to continue the
programming operation.
Further issuing of the Resume command is ignored. Another Program Suspend command
can be written after the device has resumed programming.
