Program Suspend/Program Resume Commands
The Program Suspend command allows the system to interrupt an embedded programming operation so that
data can read from any non-suspended sector. When the Program Suspend command is written during a
programming process, the device halts the programming operation within t
and updates the status bits. Addresses are “don’t-cares” when writing the Program Suspend command. After
the programming operation has been suspended, the system can read array data from any non-suspended
sector. The Program Suspend command may also be issued during a programming 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 Secured Silicon Sector area, then user must use the proper command
sequences to enter and exit this region. The system may also write the autoselect command sequence when
the device is in Program Suspend mode. The device allows reading autoselect codes in the suspended
sectors, since the codes are not stored in the memory array. When the device exits the autoselect mode, the
device reverts to Program Suspend mode, and is ready for another valid operation. See “Autoselect
Command Sequence” for more information. After the Program Resume command is written, the device
reverts to programming. The system 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 (address bits are “don’t care”) to exit the
Program Suspend mode and continue the programming operation. Further writes of the Program Resume
command are ignored. Another Program Suspend command can be written after the device has resumed
programming.
