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 in word mode (or address AAh in byte mode), any time the device is ready to read array data. The system
can read CFI information at the addresses given in
terminate reading CFI data, the system must write the reset command.The CFI Query mode is not accessible
when the device is executing an Embedded Program or embedded Erase algorithm.
The system can also write the CFI query command when the device is in the autoselect mode via the
command register only (high voltage method does not apply). The device enters the CFI query mode, and the
system can read CFI data at the addresses given in
system must write the reset command to return to reading array data.
For further information, please refer to the CFI Specification and CFI Publication 100. Contact your local sales
office for copies of these documents.
