Abstract

The embodiment of the invention discloses a flash memory data refreshing method and device, relates to the technical field of flash memory refreshing, and is used for solving the problem that a flashmemory data refreshing mechanism in the prior art may cause that the data storage duration of part of flash memory blocks exceeds the reliable storage duration. The method comprises the steps of obtaining a data storage time length of each flash memory block of terminal equipment; judging whether a to-be-refreshed flash memory block exists or not, wherein the to-be-refreshed flash memory block isa flash memory block of which the data storage time length is greater than the threshold time length; if it is determined that the to-be-refreshed flash memory block exists, judging whether the stateof the terminal device meets a preset condition or not; and refreshing the data stored in the to-be-refreshed flash memory block under the condition of determining that the state of the terminal device meets a preset condition. The embodiment of the invention is used for refreshing the data stored in the flash memory.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of flash memory refreshing, and in particular, to a flash memory data refreshing method and device. Background technique [0002] With the popularization of electronic equipment, electronic equipment has become indispensable in people's life. Generally, the storage medium in an electronic device is a flash memory (Flash memory) in a non-volatile memory, and a user can store data such as photos, documents, and personal information through the flash memory in the electronic device. [0003] As people's demand for storage capacity increases day by day, a single flash memory block can store more and more data bits. However, the increase in the number of data bits stored in the flash memory block will shorten the time for storing data in the flash memory block. If the data stored in the flash memory block is not refreshed in time, it will cause data loss or damage, and bring data loss t...
