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