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-indepen-
dent, JEDEC ID-independent, and forward- and back-
ward-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

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 6 on page

to return the device to the autoselect mode.

cation and CFI Publication 100, available via the World
Wide Web at

tative for copies of these documents.
