Abstract

The present invention discloses a data storage method, a data reading method and an electronic device to solve the technical problem that a data storage method is not flexible, to increase the rate of obtaining metadata, and to improve data processing efficiency. The data storage method comprises generating first metadata according to a first command sent by the electronic device, wherein the first metadata are data for describing attributes of data stored in a flash memory of the electronic device; determining whether a first-stage cache region for storing the first metadata satisfies a predetermined condition; and if the predetermined condition is satisfied, storing the first metadata in the first-stage cache region, or if the predetermined condition is not satisfied, storing the first metadata in a second-stage cache region, wherein the first-stage cache region and the second-stage cache region are different cache regions.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data storage method, a data reading method and electronic equipment. Background technique [0002] During the operation of electronic equipment, a large amount of metadata will be generated. Metadata is generally stored in Static Random Access Memory (SRAM) in electronic equipment, so as to facilitate fast storage and reading through the fast data processing capability of SRAM. Metadata fetching, with the improvement of the operating capability of electronic equipment, the generated metadata is gradually increasing, but due to the limited storage space of SRAM, it cannot meet the storage space requirements of more and more metadata. [0003] Alternatively, the metadata can also be directly stored in the memory of the electronic device, and when the metadata needs to be obtained, it needs to be read directly from the memory. Since the metadata needs to be read frequently an...
