Problems solved by technology

Each page of the EEPROM chip can be erased and written about 1 million times. If the number of erasing and writing of a certain page exceeds the maximum number of erasing and writing, the EEPROM cannot be used.
[0003] In related technologies, the data that needs to be repeatedly erased and written is stored in a fixed

Embodiment Construction

[0061] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

[0062] figure 1 It is a flowchart of a data modification method shown according to an exemplary embodiment, and the data modification method is applied to an electronic device, and includes the following steps.

[0063] Step S11 , receiving a data modifying instruction issued by a user, the modifying data instruction being used to represent modifying the original data stored in the...

Abstract

The invention provides a data modification method and device. The method includes the steps: receiving modified data instructions transmitted by users; switching data states of initial data into ineffectiveness from effectiveness; storing target data to idle storage spaces of storage chips; switching data states of the target data into effectiveness from ineffectiveness. The modified data instructions are used for representing that initial data stored in the storage chips are modified into the target data. When the users frequently transmit the modified data instructions according to the same data, the methods are repeated, and the frequently modified target data is stored in the storage chips in a rolling manner. When the data need to be wiped, storage positions of each wiped data are different from previous data storage positions. The data modification method solves the problem that the service lives of the storage chips are shortened as fixed positions are frequently wiped when the data are stored at the fixed positions in the storage chips.

Description

technical field [0001] The present disclosure relates to the field of data storage, in particular to a method and device for modifying data. Background technique [0002] Memory chips generally have a certain lifespan, and their lifespan is limited by the number of times of erasing and writing. For example, EEPROM (Chinese: Electrically Erasable Programmable Read-Only Memory, English: Electrically Erasable Programmable Read-Only Memory) chip, EEPROM is a memory chip that does not lose data after power failure, and can be erased on a computer or other professional equipment. Delete, rewrite. Each page of the EEPROM chip can be erased and written about 1 million times. If the number of erasing and writing of a certain page exceeds the maximum number of erasing and writing, the EEPROM cannot be used. [0003] In related technologies, the data that needs to be repeatedly erased and written is stored in a fixed position in the memory chip, then this fixed position will be repea...
