WRITE COMMANDS/COMMAND SEQUENCES
To program data to the device or erase sectors of memory , the system must drive WE and CE to
VIL, and OE to VIH.
An erase operation can erase one sector, multiple sectors , or the entire device. A "sector
address" consists of the address bits required to uniquely select a sector. Writing specific
address and data commands or sequences into the command register initiates device operations.
Table A defines the valid register command sequences. Writing incorrect address and data
values or writing them in the improper sequence resets the device to reading array data. Section
has details on erasing a sector or the entire chip, or suspending/resuming the erase operation.
After the system writes the Automatic Select command sequence, the device enters the
Automatic Select mode. The system can then read Automatic Select codes from the internal
register (which is separate from the memory array) on Q7-Q0. Standard read cycle timings apply
in this mode. Refer to the Automatic Select Mode and Automatic Select Command Sequence
section for more information.
ICC2 in the DC Characteristics table represents the active current specification for the write
mode. The "AC Characteristics" section contains timing specification table and timing diagrams
for write operations.
