ADVANCE INFORMATION
APPENDIX C
COMMON FLASH INTERFACE QUERY STRUCTURE
This appendix defines the data structure or
“database” returned by the Common Flash Interface (CFI) Query
command. System software should parse this structure to gain critical information such as block size, density,
x8/x16, and electrical specifications. Once this information has been obtained, the software will know which
command sets to use to enable flash writes, block erases, and otherwise control the flash component. The
Query is part of an overall specification for multiple command set and control interface descriptions called
Common Flash Interface, or CFI.
C.1
QUERY STRUCTURE OUTPUT
The Query “database” allows system software to gain critical information for controlling the flash component.
This section describes the device’s CFI
-
compliant interface that allows the host system to access Query data.
Query data are always presented on the lowest
-
order data outputs (DQ
0-7
) only. The numerical 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 bytes of the Query structure, “Q”, ”R”, and “Y” in ASCII, appear on
the low byte at word addresses 10h, 11h, and 12h. This CFI-compliant device outputs 00H data on upper
bytes. Thus, the device outputs ASCII “Q” in the low byte (DQ
0-7
) and 00h in the high byte (DQ
8-15
).
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.
In all of the following tables, addresses and data are represented in hexadecimal notation, so the “h” suffix
has been dropped. In addition, since the upper byte of word
-
wide devices is always “00h,” the leading “00”
has been dropped from the table notation and only the lower byte value is shown. Any x16 device outputs can
be assumed to have 00h on the upper byte in this mode.
