The command register and all internal program/erase circuits are disabled, and the device resets
to reading array data. Subsequent writes are ignored until VCC is greater than VLKO. The system
must provide the proper signals to the control inputs to prevent unintentional writes when VCC is
greater than VLKO.
Write Pulse “Glitch Protection”
Noise pulses of less than 3 ns (typical) on OE#, CE# or WE# do not initiate a write cycle.
Power-Up Write Inhibit
If WE# = CE# = RESET# = VIL and OE# = VIH during power up, the device does not accept com-
mands on the rising edge of WE#. The internal state machine is automatically reset to the read
mode on power-up.
Common Flash Memory Interface (CFI)
The Common Flash Interface (CFI) specification outlines device and host system software inter-
rogation handshake, which allows specific vendor-specified software algorithms to be used for
entire families of devices. Software support can then be device-independent, JEDEC ID-indepen-
dent, and forward- and backward-compatible for the specified flash device families. Flash vendors
can standardize their existing interfaces for long-term compatibility.
This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to
address 55h any time the device is ready to read array data. The system can read CFI information
at the addresses given in Tables 8-11. To terminate reading CFI data, the system must write the
reset command.
The system can also write the CFI query command when the device is in the autoselect mode.
The device enters the CFI query mode, and the system can read CFI data at the addresses given
in Tables 8-11. The system must write the reset command to return the device to the autoselect
mode.
