database structure to obtain information about the flash device, such as block size,
density, bus width, and electrical specifications. The system software will then know
which command set(s) to use to properly perform flash writes, block erases, reads and
otherwise control the flash device.
Query Structure Output
The Query database allows system software to obtain information for controlling the
flash device. This section describes the device’s CFI-compliant interface that allows
access to Query data.
Query data are presented on the lowest-order data outputs (DQ
offset value is the address relative to the maximum bus width supported by the device.
On this family of devices, the Query table device starting address is a 10h, which is a
word address for x16 devices.
For a word-wide (x16) device, the first two Query-structure bytes, ASCII “Q” and “R,”
appear on the low byte at word addresses 10h and 11h. This CFI-compliant device
outputs 00h data on upper bytes. The device outputs ASCII “Q” in the low byte (DQ
and 00h in the high byte (DQ
At Query addresses containing two or more bytes of information, the least significant
data byte is presented at the lower address, and the most significant data byte is
presented at the higher address.
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.
