Embodiment Construction

[0043] A method for increasing the service life of a FLASH used for storing user data. The method includes: dividing FLASH into more than two storage units, the data storage area of ​​each storage unit can completely store user data, and each time the user data is updated, the updated user data is stored in another non-current In the storage unit, more than two storage units are used to store user data in turn, instead of storing content in a fixed storage unit, causing a certain storage unit to be repeatedly read and written, so that the storage unit is recycled, avoiding a certain storage unit. The repeated use of the storage unit causes bad sectors to appear in the FLASH memory, which improves the service life of the FLASH memory. The above-mentioned method for improving the service life of FLASH can be applied to televisions using FLASH to store data, and other embedded devices with frequent data reading and writing, relatively fixed data length, and use of FLASH storage, ...

Abstract

The invention discloses a method for improving the service life of FLASH, wherein the FLASH is used for storing user data; the FLASH is divided into more than two storage units capable of completely storing the user data; more than two storage units store the data in turn instead of storing contents for a fixed storage unit, so that some storage unit is repeatedly read and written and the storage units are reused, thereby preventing the FLASH from the emergence of bad sectors because some storage unit is repeatedly used and improving the service life of the FLASH.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method for increasing the service life of FLASH. Background technique [0002] With the development of electronic technology, the functions of electronic devices are becoming more and more abundant. In order to realize the functions of electronic devices, people need to store various data in the storage chips of corresponding electronic devices, and FLASH memory is generally used for storage. [0003] FLASH memory, also known as flash memory, is a non-volatile memory widely used in embedded systems. It combines the strengths of read-only memory (ROM) and random access memory (RAM), and not only has the performance of electronic erasable and programmable , It can also read data quickly, so that the data will not be lost due to power failure. [0004] The FLASH memory can be read and written. Before the write operation, it must be erased first. The FLASH memory is erased in...
