APPENDIX B. COMMON FLASH INTERFACE
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 Read CFI Query Command is issued
the device enters CFI Query mode and the data
structure is read from the memory. Tables 31, 32,
dresses used to retrieve the data. The Query data
is always presented on the lowest order data out-
puts (DQ0-DQ7), the other outputs (DQ8-DQ15)
are set to 0.
The CFI data structure also contains a security
area where a 64 bit unique security number is writ-
Map). This area can be accessed only in Read
mode by the final user. It is impossible to change
the security number after it has been written by
ST. Issue a Read Array command to return to
Read mode.
Table 31. Query Structure Overview
Note: The Flash memory display the CFI data structure when CFI Query command is issued. In this table are listed the main sub-sections
detailed in Tables 32, 33, 34, and 35. Query data is always presented on the lowest order data outputs.
