ABSTRACT:
A memory power supply circuit configured for supplying power to two types of memories slots of a motherboard includes a slot detecting terminal configured to connect with a detecting pin of the motherboard which is used to detect the memory slots, an electrical switch element, a first resistor, a second resistor, a third resistor, and a voltage output terminal connected to power input pins of the two types of memories slots. The second resistor and third resistor are connected in series between a first power supply and ground. The slot detecting terminal is connected to a first terminal of the electrical switch element. A second terminal of the electrical switch element is grounded. A third terminal of the electrical switch element is connected to the voltage output terminal via the first resistor and connected to a node between the second and third resistors.
