Power-Up Write Inhibit
If WE# = CE# = VIL and OE# = VIH during power up, the device does not accept commands on
the rising edge of WE#. The internal state machine is automatically reset to reading array data
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 in word mode (or address AAh in byte mode), any time the device is ready to read
mode, the upper address bits (A7–MSB) must be all zeros. 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
mode.
