Function
Serial Bus Data
This is a bidirectional pin used to transfer data into or out of the SPD
EEPROM. A resistor must be connected from SDA to
motherboard to act as a pull-up.
Serial Address Select Bus 2:0
Address pins used to select the Serial Presence Detect base address.
I/O Reference Voltage
Reference voltage for the SSTL-18 inputs.
EEPROM Power Supply
Power supplies for core, I/O, Serial Presence Detect, and ground for the
module.
I/O Driver Power Supply
Power Supply
Power supplies for core, I/O, Serial Presence Detect, and ground for the
module.
Ground Plane
Power supplies for core, I/O, Serial Presence Detect, and ground for the
module.
On-Die Termination Control 0
On-Die Termination Control 1
Asserts on-die termination for DQ, DM, DQS, and DQS signals if enabled via
the DDR2 SDRAM mode register.
