Write Buffer Programming Operation
6.5.3
Sector Erase
The sector erase function erases one or more sectors in the memory array. (See
Table 11.1
and
Figure 6.4
.)
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 pattern 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. During 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
. Any sector erase address and command
following the exceeded time-out (t
SEA
) may or may not be accepted. Any command other than Sector Erase
or Erase Suspend during the time-out period resets that bank to the read mode. The system can monitor DQ3
