2. 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. The device features an Unlock Bypass mode to facilitate faster
programming. Once the device enters the Unlock Bypass mode, only two write cycles are
required to program a byte, instead of four. The "byte Program Command Sequence"
section has details on programming data to the device using both standard and Unlock
Bypass command sequences. An erase operation can erase one sector, multiple sectors,
or the entire device. Table indicates the address space that each sector occupies. A
"sector address" consists of the address bits required to uniquely select a sector. The
"Writing specific address and data commands or sequences into the command register
initiates device operations. Figure 1 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.
