during the sector erase time-out, the device immedi-
ately terminates the time-out period and suspends the
erase operation.
After the erase operation has been suspended, the
device enters the erase-suspend-read mode. The sys-
tem can read data from or program data to any sector
not selected for erasure. (The device “erase sus-
pends” all sectors selected for erasure.) Reading at
any address within erase-suspended sectors pro-
duces status information on DQ7–DQ0. The system
can use DQ7, or DQ6 and DQ2 together, to determine
if a sector is actively erasing or is erase-suspended.
Refer to the Write Operation Status section for infor-
mation on these status bits.
After an erase-suspended program operation is com-
plete, the device returns to the erase-suspend-read
mode. The system can determine the status of the
program operation using the DQ7 or DQ6 status bits,
just as in the standard byte program operation.
Refer to the Write Operation Status section for more
information.
In the erase-suspend-read mode, the system can also
issue the autoselect command sequence. Refer to the
Autoselect Mode and Autoselect Command Sequence
sections for details.
To resume the sector erase operation, the system
must write the Erase Resume command. The address
of the erase-suspended sector is required when writ-
ing this command. Further writes of the Resume com-
mand are ignored. Another Erase Suspend command
can be written after the chip has resumed erasing.
