Figure 8.4 Write Buffer Programming Operation
8.5.3
Sector Erase
The sector erase function erases one or more sectors in the memory array. (See
Table 13.1
and
Figure 8.5
) The device does not require the system to preprogram prior to erase. The Embedded
Erase algorithm automatically programs and verifies the entire memory for an all zero data pat-
tern prior to electrical erase. After a successful sector erase, all locations within the erased sector
contain FFFFh. The system is not required to provide any controls or timings during these
operations.
After the command sequence is written, a sector erase time-out of no less than t
SEA
occurs. Dur-
ing the time-out period, additional sector addresses and sector erase commands may be written.
Loading the sector erase buffer may be done in any sequence, and the number of sectors may be
from one sector to all sectors. The time between these additional cycles must be less than t
SEA
.
