Appendix B: Common Flash Interface
The Common Flash Interface is a JEDEC approved,
standardized data structure that can be read from flash
memory devices. This interface allows 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 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, through and Table 45, page 70 show
the addresses used to retrieve the data. The Query data is
always presented on the lowest order data outputs
(DQ7–DQ0), the other outputs (DQ15–DQ8) are set to ‘0’.
The CFI data structure also contains a security area where
a unique 64-bit security number is written (Figure 8,
page 22). The security number cannot be changed and can
only be accessed in Read mode. Read Array command is
used to return to Read mode.

Notes:
1.
The flash memory displays the CFI data structure when CFI Query command is issued. This table lists the main sub-sections detailed in
Table 38, page 66, and Table 41, page 68. Query data is always presented on the lowest order data outputs.
