accept another command.
The sector erase architecture allows memory sectors to be
erased and reprogrammed without affecting the data contents
of other sectors. The A29040A 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.
