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 in Table D3.

The following sections describe the Query structure sub-sections in detail.

NOTES:

1. Refer to Section D.1 and Table D1 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.
