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 Table 8.1 to Table 8.4 on page 23. In word 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 in Table 8.1 to
Table 8.4 on page 23. The system must write the reset command to return the device to the autoselect mode.
For further information, please refer to the CFI Specification and CFI Publication 100, available via the World
Wide Web at http://www.amd.com/products/nvd/overview/cfi.html. Alternatively, contact a Spansion
representative for copies of these documents.
