Description
Row bus. 3-bit bus containing control and address information
for row accesses. Connects to right RDRAM device on "Thru"
Channel.
Serial Clock input. Clock source used to read from and write
to "Thru" Channel RDRAM control registers. Connects to left
RDRAM device on "Thru" Channel.
Serial Clock input. Clock source used to read from and write
to "Thru" Channel RDRAM control registers. Connects to right
RDRAM device on "Thru" Channel.
"Thru" Channel Serial I/O for reading from and writing to the
control registers. Attaches to SIO0 of right RDRAM device on
"Thru" Channel.
"Thru" Channel Serial I/O for reading from and writing to the
control registers. Attaches to SIO1 of left RDRAM device on
"Thru" Channel.
Clock from master. Connects to right RDRAM device on
"Term" Channel. Interface clock used for receiving RSL
signals from the controller. Positive polarity.
Clock from master. Connects to right RDRAM device on
"Term" Channel. Interface clock used for receiving RSL
signals from the controller. Negative polarity.
Serial Command Input used to read from and write to the
control registers. Also used for power management.
Connects to right RDRAM device on "Term" Channel.
"Term" Channel Column bus. 5-bit bus containing control and
address information for column accesses. Connects to right
RDRAM device on "Term" Channel.
Clock To Master. Connects to left RDRAM device on "Term"
Channel. Interface clock used for transmitting RSL signals to
the controller. Positive polarity.
Clock To Master. Connects to right RDRAM device on "Term"
Channel. Interface clock used for transmitting RSL signals to
the controller. Positive polarity.
Clock To Master. Connects to left RDRAM device on "Term"
Channel. Interface clock used for transmitting RSL signals to
the controller. Negative polarity.
Clock To Master. Connects to right RDRAM device on "Term"
Channel. Interface clock used for transmitting RSL signals to
the controller. Negative polarity.
"Term" Channel Data bus A. A 9-bit bus carrying a byte of
read or write data between the controller and RDRAM devices
on “Term” Channel. Connects to right RDRAM device on
"Term" Channel. DQA8_TERM is non-functional on modules
with x16 RDRAM devices.
"Term" Channel Data bus B. A 9-bit bus carrying a byte of
read or write data between the controller and RDRAM devices
on “Term” Channel. Connects to right RDRAM device on
"Term" Channel. DQB8_TERM is non-functional on modules
with x16 RDRAM devices.
"Term" Channel Row bus. 3-bit bus containing control and
address information for row accesses. Connects to right
RDRAM device on "Term" Channel.
Serial Clock input. Clock source used to read from and write
to "Term" Channel RDRAM control registers. Connects to
right RDRAM device on "Term" Channel.
"Term" Channel Serial I/O for reading from and writing to the
control registers. Attaches to SIO0 of left RDRAM device on
"Term" Channel.
"Term" Channel Termination voltage.
