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 A11 to A18 = 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 A18, A17, A16, A15, A14, A13, and A12 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 A0 to A10
Byte Mode: AAAH or 555H to addresses A–1 and A0 to A10
6. Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
