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.

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 = The beginning location of a Block Address (e.g., 08000h is the beginning location of block 1
when the block size is 32 Kword).
3.
Offset 15 defines “P” which points to the Primary Intel-specific Extended Query Table.
