Data storage method, reading method and system for extending memory usage time

Abstract

The invention discloses a data storage method, reading method and systems for prolonging the service life of a memory.The data storage method includes the steps that firstly, one or more storage areas are allocated for data to be stored in the memory in advance; secondly, in the data storage process, the data to be stored is stored in the memory in the mode that the storage areas are switched in turn.The data reading method includes the steps that firstly, marking variables FLAG in the storage areas are read; secondly, according to the marking variables FLAG of the storage areas, the storage area where the latest data is located is judged; thirdly, data of the storage area corresponding to a judgment result is read to serve as effective data.The storage system comprises a storage area allocation module and a data processing module.The reading system comprises a marking variable reading module, a judgment module and an execution module.The utilization rate of the memory is maximized through the methods, system design requirements can still be met even if a memory low in number of operation times is selected and used, and accordingly cost is lowered.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, and more specifically relates to a data storage method, a reading method and a system for prolonging the service time of a memory. Background technique [0002] In recent years, with the development of information technology, the security of data stored on storage media and the ability to restore data have attracted increasing attention, which puts forward higher and higher requirements for the service life of storage media for storing data to ensure that The data is not damaged, and it is also hoped that the accidentally deleted data can be recovered in the case of misoperation or virus infestation. In the prior art, when data is stored, the erasing and writing operations are frequently repeated on a certain area in the memory, while other storage areas rarely or never perform erasing and writing operations, resulting in low memory usage, and ultimately lead to long memory usage time. ...

AI Technical Summary

Problems solved by technology

In the prior art, when data is stored, the erasing and writing operations are frequently repeated on a certain area in the memory, while other storage areas rarely or never perform erasing and writing operations, resulting in low memory usage, and ultimately lead to long memory usage time. Short, for data streams that need to be stored frequently, the life of the memory may not meet the system design requirements

In addition, in some applications that need to replace the hardware, the data in the original system may be lost after the replacement of the hardware
