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 de-
v i c e s. S o f t wa r e s u p p o r t c a n t h e n b e d ev i c e -
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 sys-
tem 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 sys-
tem must write the reset command to return the device
to the autoselect mode.

cation and CFI Publication 100, available via the World
