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 CFI
Query Command is issued the device enters CFI Query mode and the data structure is read from the
memory.

The CFI data structure also contains a security area where a 64 bit unique security number is written
