19 Appendix 1
19.1
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 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 19.1-Table
19.3. In order 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 19.1-Table 19.3. 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 or contact a
Spansion representative for copies of these documents.
