APPENDIX B. COMMON FLASH INTERFACE (CFI)
The Common Flash Interface is a JEDEC ap-
proved, 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 mem-
ory. The system can interface easily with the de-
vice, enabling the software to upgrade itself when
necessary.
When the CFI Query Command is issued the de-
vice enters CFI Query mode and the data structure
is read from the memory. Tables 22, 23, 24, 25, 26
Table 22. Query Structure Overview
Note: Query data are always presented on the lowest order data outputs.
Table 23. CFI Query Identification String
Note: Query data are always presented on the lowest order data outputs (DQ7-DQ0) only. DQ8-DQ15 are ‘0’.

and 27 show the addresses used to retrieve the
data.
The CFI data structure also contains a security
area where a 64 bit unique security number is writ-
ten (see Table 27, Security Code area). This area
can be accessed only in Read mode by the final
user. It is impossible to change the security num-
ber after it has been written by Numonyx. Issue a
Read command to return to Read mode.
Note: The Common Flash Interface is only avail-
able for Temperature range 6 (–40 to 85°C).
