10. 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 any time the device is ready to read array data. The system can read CFI information at the addresses
given in Tables Table 10.2–Table 10.5. To terminate reading CFI data, the system must write the reset
command.
For further information, please refer to the CFI Specification (see JEDEC publications JEP137-A and
JESD68.01). Please contact your sales office for copies of these documents.
