Data updating method and device

Abstract

The embodiment of the invention provides a data updating method and device. The data updating method comprises the steps that an access request for an embedded database in a Flash storage chip is received, and first data in the embedded database is determined and then saved in a memory space, wherein when the access request for the first data is received, the first data in the memory space is read, written and then updated to the Flash storage chip after a set time period. According to the method, when a read-write operation is conducted on the first data in the embedded database, the first data is not updated to the Flash storage chip after each time of the read-write operation but saved in the memory space, the read-write operation on the first data is executed in the memory space, the first data is updated to the Flash storage chip after the set time period, therefore, the erasing frequency of the Flash storage chip is significantly decreased, then the service life of the Flash storage chip is prolonged, and the equipment maintenance cost is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer data processing, and in particular, to a method and device for updating data. Background technique [0002] With the increasing application of embedded products, their short service life is also gradually reflected. Often a device has to be retired from the front line due to equipment aging and other reasons within a few years. One of the important factors is the aging of memory chips. Flash memory chips have a clear limit on the number of erasing and writing times when they are produced. Many products on the market do not fully consider the economical use of Flash life during their development stage. Excessive erasing will destroy the storage area of ​​​​the Flash memory chip and eventually lead to data loss. , Embedded programs cannot run normally and other fatal problems. An embedded device often has a lot of hardware and software combined to achieve its specific functions. T...

Problems solved by technology

Flash memory chips have a clear limit on the number of erasing and writing times when they are produced. Many products on the market do not fully consider the economical use of Flash life during their development stage. Excessive erasing will destroy the storage area of ​​​​the Flash memory chip and eventually lead to data loss. , Embedded programs cannot run normally and other fatal problems

An embedded device often has a lot of hardware and software combined to achieve its specific functions. Due to the unreasonable use of the Flash memory chip, the entire product is scrapped, which ultimately results in a great waste of resources.
