Query Structure Overview

The Query command causes the flash component to display the Common Flash Interface (CFI)

Query structure or database. Table 32 summarizes the structure sub-sections and address

locations.

Table 32: Query Structure

00001-Fh Reserved

Reserved for vendor-specific information

00010h CFI query identification string

Command set ID and vendor data offset

0001Bh System interface information

Device timing & voltage information

00027h Device geometry definition

Flash device layout

P(3)

Vendor-defined additional information specific

Primary Numonyx-specific Extended Query to the Primary Vendor Algorithm

Note:

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 = Block Address beginning location (i.e., 08000h is block 1’s beginning location when the block size is 32-KWord).

3.

Offset 15 defines “P” which points to the Primary Numonyx-specific Extended Query Table.

A.1.3

Read CFI Identification String

The Identification String provides verification that the component supports the

Common Flash Interface specification. It also indicates the specification version and

supported vendor-specified command set(s).
