Table 36: Example of Query Structure Output of x16- Devices
C.2
Query Structure Overview
The Query command causes the flash component to display the Common Flash
Interface (CFI) Query structure or “database.” The structure sub-sections and address
locations are summarized below.
Table 37: Query Structure
Notes:
1.
Refer to the Query Structure Output section and offset 28h for the detailed definition of offset address as a function of
device bus width and mode.
2.
BA = Block Address beginning location (i.e., 08000h is block 1’s beginning location when the block size is 32-KWord).
3.
Offset 15 defines “P” which points to the Primary Numonyx-specific Extended Query Table.
C.3
CFI Query Identification String
The Identification String provides verification that the component supports the
Common Flash Interface specification. It also indicates the specification version and
supported vendor-specified command set(s).
