Table 24. Example of Query Structure Output of a x16- and x8-Capable Device
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. See AP-646 Common Flash Interface (CFI) and Command Sets (order number 292204) for
a full description of CFI commands.
The following sections describe the Query structure sub-sections in detail.

NOTE:
1. The system must drive the lowest order addresses to access all the device's array data when the device is

configured in x8 mode. Therefore, word addressing, where these lower addresses are not toggled by the
system, is "Not Applicable" for x8-configured devices.
