Preliminary
Appendix C Common Flash Interface
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 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 (DQ0-7) 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 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
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.
