Embodiment Construction

[0012] see figure 1 and figure 2 , a kind of memory power supply system 100 provided for the embodiment of the present invention, comprises a power supply 10, a plurality of memory slots 20 (slot 1, slot 2, slot 3 ... slot N), a baseboard management controller 30 (baseboard management controller, BMC), memory 40 whose quantity corresponds to the plurality of memory slots 20, and pull-up resistors 50 whose quantity corresponds to the plurality of memory slots 20.

[0013] The power supply 10 is used for providing a first DC voltage to each memory slot 20 . In this implementation manner, the first direct current voltage is a direct current voltage of 12 volts.

[0014] Each memory slot 20 is used for correspondingly loading a memory 40 . Each memory slot 20 includes a first ground pin 201 and a first power pin 202 . Each first ground pin 201 is connected to the power supply 10 through a corresponding pull-up resistor 50 . Each of the first ground pins 201 is also electrica...

Abstract

The invention relates to a memory with a rated voltage and a rated power. The memory is installed in a memory slot; the memory slot comprises a first grounding pin and a first power supply pin; the first grounding pin and the first power supply pin are electrically connected to a power supply; and the power supply is used for supplying a first direct current voltage. The memory comprises a second grounding pin, a second power supply pin and a step down voltage regulator; the second grounding pin is electrically connected to the first grounding pin; the second power supply pin is electrically connected to the first power supply pin; the output power of the step down voltage regulator is corresponding to the rated power; and the step down voltage regulator is electrically connected to the second power supply pin and is used for converting the first direct current voltage to the rated voltage. The step down voltage regulator is only corresponding to one memory, namely, the step down voltage regulator works under the full load condition, the conversion efficiency of electric energy of the step down voltage regulator can be improved. The invention also provides a memory power supply system with the memory.

Description

technical field [0001] The invention relates to a memory and a memory power supply system with the memory. Background technique [0002] Computer motherboards usually include a voltage regulator down (VRD) for converting voltage. The external power supply supplies power to the memory after passing through the step-down regulator. When designing computer motherboards, the output power of the buck regulator is generally designed to be equal to or slightly greater than the sum of the working power when the number of memory is the largest, so as to meet the power supply demand. At present, the number of memory on the computer motherboard is increasing, so the output power of the buck regulator is also increasing. However, in general, if the load of the buck regulator is smaller (meaning that the number of loaded memories is less than or even much smaller than the maximum number set during design), the power conversion efficiency will be lower and the load will be larger (for e...
