QUERY STRUCTURE OVERVIEW
The Query command causes the flash component to display the Common Flash Interface (CFI) Query
structure or
“database.” See
AP-646 Common Flash Interface (CFI) and Command Sets
(order number
292204) for a full description of CFI.
The following sections describe the Query structure sub-sections in detail.

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.
BA = Block Address beginning location (i.e., 02000h is block 2’s beginning location when the block size is 128 Kbyte).
Offset 15 defines “P” which points to the Primary Intel-Specific Extended Query Table.
