Abstract

The invention provides a method and a device for realizing a solid state drive based on a host memory buffer. The method comprises the following steps that: a solid state drive SSD applies for allocating a host memory buffer HMB space to a host; and caches a mapping table of the SSD in the HMB space; and when a host operation instruction is executed, the mapping table cached in the HMB space is operated to realize the operation of the flash memory particles in the SSD. According to the technical scheme of the embodiment of the invention, the hardware size and power consumption can be reduced,and the hardware cost is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for implementing a solid-state drive based on a host memory buffer. Background technique [0002] A solid state drive (SSD), also known as a solid-state drive, is a hard drive made of an array of solid-state electronic memory chips. Solid-state drives are widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and many other fields. [0003] A traditional SSD consists of a storage controller, a cache, and flash memory particles. The SSD has a built-in cache to ensure product performance. At present, the buffers in SSDs are usually implemented by dynamic random access memory (DRAM). For SSDs using DRAM as buffers, although the performance can be effectively improved, the hardware size is increased and the power consumption is also high. ...
