QUERY STRUCTURE OVERVIEW
20
PRELIMINARY
4.2.2
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. 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 Query Data Output section of Device Hardware interface for the detailed definition of offset address as a function
of device word width and mode.
2. BA = The beginning location of a Block Address (i.e., 2000h is the beginning location of block 2 when the block size is
128 KB).
3. The Primary Vendor-Specific Extended Query table (P) address may change among SCS-compliant devices. Software
should retrieve this address from address 15 to guarantee compatibility with future SCS-compliant devices.
