Abstract

The invention discloses a memory, a data storage method and a data reading method, and the memory comprises at least one erasing block, each erasing block comprises a mapping information storage area and at least one data information storage area corresponding to the mapping information storage area; the data information storage area is used for storing data information, the mapping information storage area is used for storing mapping information, the mapping information reflects data write-in states of all the data information storage areas corresponding to the mapping information storage area, and the data information is information needing to be stored in the memory. Compared with the prior art, the scheme does not need to erase the content of the whole erasure block every time the data is written, repeated erasure of the memory is avoided, and the service life of the memory is prolonged.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a memory, a data storage method and a data reading method. Background technique [0002] With the rapid development of computer technology, more and more attention has been paid to data processing and storage. At present, a storage medium such as a Flash memory is usually used for data storage. In an embedded system, it is usually necessary to save some parameters and other information to the controller, so memory is usually set in the controller for data storage. [0003] Specifically, in the prior art, a whole area is usually allocated in the memory for data storage. When storing data, the entire storage area is erased first, and then the data is written. When the data is read , to read from a fixed position. The problem with the prior art is that it is impossible to know whether the area is full of data, so the entire area needs to be erased every time data is written, wh...
