Abstract
A method of improving memory power efficiency is disclosed. The method includes the following steps: a ground pin of a memory socket connecting to a power source, the ground pin is connected to a controller; the ground pin outputting a high level signal to the controller when the memory socket is without a memory component; and the controller sending an off-command to a regulator to cut off a supplying power to the memory socket after the controller receives the high level signal.
Claims19
A method comprising:
- a ground pin of a memory socket connecting to a power source, the ground pin is connected to a controller;
- the ground pin outputting a high level signal to the controller when the memory socket is without a memory component;
- and
- the controller sending an off-command to a regulator to cut off a supplying power to the memory socket after the controller receives the high level signal.

A system of improving memory power efficiency comprising:
- a memory socket having a ground pin connecting to a power voltage through a resistor;
- a baseboard management controller (BMC) connected to the ground pin, wherein the BMC receives a low level signal from the ground pin when a memory component is mounted in the memory socket and the BMC receives a high level signal from the ground pin when the memory socket is unused;
- and
- a voltage regulator down (VRD) is connected to the BMC to supply power to the memory socket depending on an on command of the BMC after the BMC receives the low level signal.
