Appendix B
The Common Flash Interface is a JEDEC approved, standardized data structure that can be read from
the Flash memory device. It allows a system software to query the device to determine various electrical
and timing parameters, density information and functions supported by the memory. The system can
interface easily with the device, enabling the software to upgrade itself when necessary.
When the Read CFI Query command is issued, the memory enters Read CFI Query mode and read
operations output the CFI data.
addresses (A-1, A0-A7) used to retrieve the data.
