Problems solved by technology

In this way, even if the solid-state storage device quickly extracts the L2P table for data reading to ensure the data reading performance of the solid-state storage device, since the random access memory such as DRAM or SRAM is relatively expensive, it also greatly increases the solid-state storage capacity. Manufacturing cost of equipment

Abstract

The invention discloses a data reading method and system for solid-state storage equipment, terminal equipment and a computer storage medium, and the method comprises the steps: transmitting a physical storage address of storage data in the solid-state storage equipment to the terminal equipment through the solid-state storage equipment in communication connection with the terminal equipment; caching the physical storage address in a running memory by the terminal equipment; when a first data reading instruction issued by the terminal equipment is received, determining whether a physical storage address of to-be-read data carried in the first data reading instruction is changed or not; and if it is determined that the physical storage address does not change, reading the to-be-read data according to the physical storage address and returning the to-be-read data to the terminal device. According to the invention, the dependence of the solid-state storage device on the random access memory is eliminated, so that the solid-state storage device still has good data reading performance under the condition of not configuring the random access memory so as to reduce the generation and manufacturing cost.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a data reading method, system, terminal equipment and computer storage medium of a solid-state storage device. Background technique [0002] Currently, solid state storage devices such as SSDs (Solid State Drives, solid state drives) are widely used in the market because of their fast data access speed. When a user writes a logical address to store data based on a solid-state storage device, the master control of the solid-state storage device will find a physical page to write the user data into storage, and record the mapping relationship between the logical address and the physical storage address of the data on the physical page , so as to establish a mapping table between the logical address and the physical storage address—L2P table (L2P, that is, the mapping from logical address to physical storage address), so that the solid-state storage device can use the L...
