Power supply voltage adjusting device, method and equipment of solid state disk controller and medium

Abstract

The invention discloses a power supply voltage adjusting device, method and equipment of a solid state disk controller and a medium. The device comprises a solid state disk controller which comprisesan AVS state pin and a power supply voltage pin; a DC converter which comprises a feedback pin, an output pin connected to the power supply voltage pin, and a feedback circuit connected in parallel between the feedback pin and the output pin; a microcontroller which comprises a first pin and a second pin, wherein the first pin is connected with the AVS state pin to obtain the state of the AVS state pin, and the second pin is connected with the feedback circuit. The microcontroller is configured to adjust the feedback circuit through the second pin when the AVS state pin is invalid, so that theDC converter supplies power to the power supply voltage pin according to a first preset voltage, and adjust the feedback circuit through the second pin when the AVS state pin is valid, so that the DCconverter supplies power to the power supply voltage pin according to a second preset voltage, wherein the first preset voltage is greater than the second preset voltage. The scheme of the inventionreduces the power consumption of the solid state disk.

Description

technical field [0001] The present application relates to the field of storage, and in particular to a device, method, device and medium for adjusting a power supply voltage of a solid state disk controller. Background technique [0002] Solid State Disk (SSD) has great advantages in speed, power consumption, capacity, noise, reliability and other performance. At this stage, although the former has a certain advantage in price, but with the large capacity of FLASH With the emergence of SDD, the price of SDD will be lower and lower, making it more widely used in servers and storage devices. [0003] From the perspective of hardware components, SSDs are generally composed of core devices such as controllers, NAND flash memory chips, and DRAM (Dynamic Random Access Memory, dynamic random access memory) cache chips. Through the front-end interface, the controller interacts with the server storage and other devices on the host side, and the data of the DRAM chip is cached and re...

Problems solved by technology

For the power consumption of the entire SSD, the power consumption of the controller, DRAM, NAND and other devices occupies more than 90% of the power consumption of the entire SSD motherboard, of which the power consumption of the controller occupies a large proportion, but some SSD control Part of the device supports AVS (Adaptive Voltage Scaling, adaptive voltage regulation) function (that is, some chips support the function of reducing the core voltage, and some chips do not support the function of reducing the core voltage), how to select the AVS function in the process of hardware development and product application? It is a problem for hardware developers to adjust the core voltage of the SSD controller through hardware peripheral circuits and reduce the system power consumption of some SSDs.
