Power supply voltage adjustment device, method, device and medium for solid state disk controller

Abstract

The invention discloses a power supply voltage adjustment device, method, equipment and medium of a solid-state hard disk controller. The device includes: a solid-state hard disk controller, including an AVS status pin and a power supply voltage pin; a DC converter, including a feedback pin, an output pin connected to the power supply voltage pin, and a parallel connection between the feedback pin and the output pin. A feedback circuit between the pins; the microcontroller includes a first pin and a second pin, the first pin is connected to the AVS state pin to obtain the state of the AVS state pin, and the second pin is connected to the feedback circuit; The microcontroller is configured to adjust the feedback circuit through the second pin when the AVS status pin is inactive, so that the DC converter powers the supply voltage pin at the first preset voltage, and through the second pin when the AVS status pin is active. The pin adjusts the feedback circuit, so that the DC converter supplies power to the power supply voltage pin according to the second preset voltage, and the first preset voltage is greater than the second preset voltage. The solution of the present invention reduces the power consumption of the solid-state hard disk.

Description

technical field [0001] The present application relates to the field of storage, and in particular, to a power supply voltage adjustment device, method, device and medium of a solid-state hard disk controller. Background technique [0002] Solid State Disk (SSD) has great advantages in terms of speed, power consumption, capacity, noise, reliability and other performance. 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, an SSD is generally composed of core devices such as a controller, a NAND flash memory chip, and a DRAM (Dynamic Random Access Memory, dynamic random access memory) cache chip. 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 read and written with the back-end NAND. The SSD controller is the core unit of the SSD, and ...

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.
