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.
