Appendix B Common Flash Interface
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 device enters CFI Query mode and the
data structure is read from the memory.
Table 36
,
Table 37
,
Table 38
,
Table 39
,
Table 40
,
Table 42
,
Table 43
,
Table 44
and
Table 45
show the addresses used to retrieve the data. The
Query data is always presented on the lowest order data outputs (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
written (see
Figure 4: Protection Register 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.

Query Structure Overview
1.
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
Table 37
,
Table 38
,
Table 39
and
Table 40
. Query data is always presented on the lowest order data
outputs.
