Program Suspend/Program Resume
Command Sequence
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 Sus-
pend command is written during a programming pro-
cess, the device halts the program operation within 15
µs max (5 µs typical) and updates the status bits. Ad-
dresses are not required when writing the Program
Suspend command.
After the programming operation has been sus-
pended, the system can read array data from any
non-suspended sector. The Program Suspend com-
mand may also be issued during a programming oper-
ation while an erase is suspended. In this case, data
may be read from any addresses not in Erase Sus-
pend or Program Suspend. If a read is needed from
the SecSi Sector area (One-time Program 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 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 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 deter-
mine the status of the program operation using the
DQ7 and DQ15 or DQ6 and DQ14 status bits, just as
in the standard program operation. See
tion Status
The system must write the Program Resume com-
mand (address bits are don’t care) to exit the Program
Suspend mode and continue the programming opera-
tion. Further writes of the Resume command are ig-
nored. Another Program Suspend command can be
written after the device has resume programming.
