Memory data reading method and device, electronic equipment and readable medium

Abstract

The invention provides a memory data reading method and device, electronic equipment and a readable medium, and the method comprises the steps: obtaining target information of a to-be-read file; the target information comprises a target page address and a target page number M occupied by the to-be-read file in a memory of the electronic equipment; and reading the target data from the memory for N times according to the target page address and the target page number M, and writing the read target data into the specified buffer area. Compared with a mode of page-by-page reading and writing and needing M times of reading and writing, in the method of the invention, the target page number M occupied by the to-be-read file in the memory and the corresponding target page address are acquired, and on the basis of the target page number M and the target page address, not only one page of data is read each time, so that the to-be-read file can be read and written only by N times of reading and writing. Therefore, the reading and writing frequency can be reduced, the reading and writing efficiency can be improved to a certain extent, and the reading and writing time consumption is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data storage, and in particular, to a memory data reading method, device, electronic equipment, and readable medium. Background technique [0002] At present, a large amount of memory, for example, a nandflash memory, is often installed in an electronic device. Wherein, the data in the nandflash memory is usually stored in units of pages, and each page stores data of a fixed size. Usually a file will occupy multiple pages in memory. Furthermore, in some operating links of the electronic device, it is often necessary to read the files stored in the nandflash memory and write them into the specified buffer area. [0003] Therefore, there is an urgent need for a method for reading data in a memory for efficient reading and writing.
