PRELIMINARY
COMMON FLASH MEMORY INTERFACE
(CFI)
The Common Flash Interface (CFI) specification out-
lines 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-inde-
pendent, 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 Tables 5–8. 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 Tables 5–8. The
system must write the reset command to return the
device to the autoselect mode.
For further information, please refer to the CFI Specifi-
cation and CFI Publication 100, available via the World
Wide Web at http://www.amd.com/products/nvd/over-
view/cfi.html. Alternatively, contact an AMD represent-
ative for copies of these documents.
