Abstract

The invention discloses a memory, a data storage method and a data reading method, wherein the memory includes: at least one erasing block, and each of the above-mentioned erasing blocks includes a mapping information storage area and at least one mapping information storage area Corresponding data information storage area; the above data information storage area is used to store data information, the above mapping information storage area is used to store mapping information, and the above mapping information reflects the data writing of all data information storage areas corresponding to the above mapping information storage area state, the above-mentioned data information is information that needs to be stored in the above-mentioned memory. Compared with the prior art, the solution of the present invention does not need to erase the contents of the entire erasing block every time data is written, avoiding repeated erasing of the memory and improving the service life of the memory.

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...
