Function
Data Masks 7:0
Note: The data write masks, associated with one data byte. In
4.
Serial Bus Clock
Note: This signal is used to clock data into and out of the SPD
Serial Bus Data
Note: This is a bidirectional pin used to transfer data into or out of
Serial Address Select Bus 1:0
Note: Address pins used to select the Serial Presence Detect base
I/O Reference Voltage
Note: Reference voltage for the SSTL-18 inputs.
Power Supply
Note: Power and ground for the DDR SDRAM
EEPROM Power Supply
Note: Serial EEPROM positive power supply, wired to a separate
8 based module
Write mode, DM operates as a byte mask by allowing input
data to be written if it is LOW but blocks the write operation
if it is HIGH. In Read mode, DM lines have no effect.
