READ UNIQUE ID (EDh) Operation
R/B#
Command
EDh
The READ UNIQUE ID (EDh) command is used to read a unique identifier programmed
into the target. This command is accepted by the target only when all LUNs on the target
are idle.
Writing EDh to the command register puts the target in read unique ID mode. The target
stays in this mode until another valid command is issued.
When the EDh command is followed by an 00h address cycle, the target goes busy for
If the READ STATUS (70h) command is used to monitor for command completion, the
READ MODE (00h) command must be used to re-enable data output mode.
After
asynchronous interface is active, one data byte is output per RE# toggle. When the
synchronous interface is active, two data bytes are output, one byte for each rising or
falling edge of DQS.
Sixteen copies of the unique ID data are stored in the device. Each copy is 32 bytes. The
first 16 bytes of a 32-byte copy are unique data, and the second 16 bytes are the comple-
ment of the first 16 bytes. The host should XOR the first 16 bytes with the second 16
bytes. If the result is 16 bytes of FFh, then that copy of the unique ID data is correct. In
the event that a non-FFh result is returned, the host can repeat the XOR operation on a
subsequent copy of the unique ID data. If desired, the CHANGE READ COLUMN (05h-
E0h) command can be used to change the data output location. Use of the SELECT
CACHE REGISTER (06h-E0h) command is prohibited.
