Program Suspend/Program Resume Commands
The Program Suspend command allows the system to interrupt an embedded programming operation or a
“Write to Buffer” 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 15 µs maximum (5 µs typical) 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 within a sector 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
After the Program Resume command is written, the device reverts to programming. The system can
determine the status of the program operation using the write operation status bits, just as in the standard
program operation. See
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.
