Common Flash Interface
The Numonyx® Omneo™ P8P PCM device borrows from the existing standards
established for flash memory, and supports the use of the Common Flash Interface
(CFI). This appendix defines the data structure or “database” returned by the CFI
Query command. System software should parse this structure to gain critical
information such as block size, density, x16, and electrical specifications. Once this
information has been obtained, the software will know which command sets to use to
enable PCM writes, block erases, and otherwise control the PCM component. The Query
is part of an overall specification for multiple command set and control interface
descriptions called Common Flash Interface, or CFI.
Query Structure Output
The Query database allows system software to obtain information for controlling the
PCM 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.
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.
