PRELIMINARY
The host system can detect whether a program or erase
operation is complete by reading the I/O
and I/O
has been completed, the device is ready to read array data
or accept another command.
The sector erase architecture allows memory sectors to be
erased and reprogrammed without affecting the data
contents of other sectors. The A29040 is fully erased when
shipped from the factory.

The hardware sector protection feature disables operations
for both program and erase in any combination of the
sectors of memory. This can be achieved via programming
equipment.
The Erase Suspend feature enables the user to put erase
on hold for any period of time to read data from, or
program data to, any other sector that is not selected for
erasure. True background erase can thus be achieved.
Power consumption is greatly reduced when the device is
placed in the standby mode.
