Query Structure Overview
The Query command causes the flash component to display the Common Flash Interface (CFI)
Query structure or “database.” Table 29 summarizes the structure sub-sections and address
locations.

Notes:
1.
Refer to the Query Structure Output section and offset 0x28 for the detailed definition of offset address
as a function of device bus width and mode.
2.
BA = Block Address beginning location (i.e., 0x08000 is block 1’s beginning location when the block
size is 32K-word).
3.
Offset 15 defines “P” which points to the Primary Intel-specific Extended Query Table.
