Function
Data Mask Bus 8:0
The data write masks, associated with one data byte. In 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.
Note: See block diagram for corresponding DQ M signals
This signal is used to clock data into and out of the SPD EEPROM.
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.
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.
