Abstract

The invention discloses a flash memory data writing method, device and computer-readable storage medium, comprising the following steps: after receiving a data writing instruction, acquiring the temperature value of the current environment; when the temperature value is not within the preset range When it is inside, write the data into the first storage area, wherein the first storage area adopts SLC programming mode to store data, and write 1Bit data each time when writing the data; when the temperature value is restored When it is within the preset range, the data in the first storage area is acquired and written into the second storage area, wherein the second storage area adopts a storage mode other than the SLC programming mode. Because the present invention can judge whether the operating temperature is within the normal range before writing data, when the temperature is not within the normal range, the data is written into the single-level storage unit, thereby solving the problem of writing data outside the normal working temperature range of the flash memory. The problem of increased data error rate.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a flash memory data writing method, device and computer-readable storage medium. Background technique [0002] In recent years, with the development of science and technology, various automated instruments and equipment have appeared in various industrial workshops and some harsh exploration environments. In order to meet the requirements of high intelligence, these instruments and equipment will generate a large number of data and use NAND flash memory for storage. [0003] However, in many cases, the environment where NAND flash memory is located is not so comfortable. For equipment working in complex industrial and exploration environments, the data stability of the equipment containing NAND flash memory is a huge test. Especially when the external environment temperature is too high or too low, the error rate will be greatly increased when writing data in the NAND flash memory. ...
