Sector Erase Suspend Erase can be suspended during sector erase with Addr. (“H” or “L”). Data (B0H)
Sector Erase Resume Erase can be resumed after suspend with Addr. (“H” or “L”). Data (30H)
Notes:
1. Address bits A
11
to A
18
= X = “H” or “L” for all address commands except or Program Address (PA)
and sector Address (SA)
2. Bus operations are defined in Tables 2 and 3.
3. RA = Address of the memory location to be read
PA = Address of the memory location to be programmed
Addresses are latched on the falling edge of the
WE
pulse.
SA = Address of the sector to be erased. The combination of A
18
, A
17
, A
16
, A
15
, A
14
, A
13
, and A
12
will uniquely select any sector.
4. RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the falling edge of
WE
.
5. The system should generate the following address patterns:
Word Mode: 555H or 2AAH to addresses A
0
to A
10
Byte Mode: AAAH or 555H to addresses A
–1
and A
0
to A
10
6. Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
