Common Flash Memory Interface (CFI)
The Common Flash Interface (CFI) specification outlines device and host system software interrogation
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-independent, 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
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
