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. Tables 23, 24, 25, 26,
used to retrieve the data.
The CFI data structure also contains a security area where a 64 bit unique security number
is written (see
by the final user. It is impossible to change the security number after it has been written by
Numonyx. Issue a Read command to return to Read mode.
