Program Suspend/Program Resume Command Sequence
February 7, 2007 S29GL-M_00_B8
The Program Suspend command allows the system to interrupt a programming operation or a
Write to Buffer programming operation so that data can be read from any non-suspended sector.
When the Program Suspend command is written during a programming process, the device halts
the program operation within 15 µs maximum (5 µs typical) and updates the status bits. Ad-
dresses are not required when writing the Program Suspend command.
After the programming operation is suspended, the system can read array data from any non-
suspended sector. The Program Suspend command can also be issued during a programming op-
eration while an erase is suspended. In this case, data can be read from any addresses not in
Erase Suspend or Program Suspend. If a read is needed from the Secured Silicon Sector area
(One-time Program area), then user must use the proper command sequences to enter and exit
this region. Note that the Secured Silicon Sector, autoselect, and CFI functions are unavailable
when a program operation is in progress.
The system can also write the autoselect command sequence when the device is in the Program
Suspend mode. The system can read as many autoselect codes as required. When the device
exits the autoselect mode, the device reverts to the Program Suspend mode, and is ready for an-
other 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 DQ7 or DQ6 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 Resume
command are ignored. Another Program Suspend command can be written after the device re-
sumes programming.
