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. The CFI data structure also contains a security area
where a 64-bit unique security number is written (see
accessed only in read mode by the final user. It is impossible to change the security number after it has
been written by Numonyx.
