Abstract

The invention provides a method and device for rewriting chip data. The method applicable to a rewriting device includes: acquiring a rewriting instruction, and entering a chip rewriting state; acquiring the configuration information of a to-be-rewritten chip, and identifying the to-be-rewritten chip; judging whether a rewriting state is a non-rewriting state or not according to the configuration information, and if so, generating corresponding codes according to the configuration information; writing the codes into the preset storage unit of the to-be-rewritten chip, and rewriting the configuration information of the chip; if the rewriting state is judged as the rewriting state according to the configuration information, directly rewriting the configuration information of the to-be-rewritten chip. The device provides an executing module for the method. By the method and device, chip data rewriting safety can be increased.

Description

technical field [0001] The present invention relates to the field of chip technology, in particular to a method for rewriting chip data, and also to a device for implementing the method for rewriting chip data. Background technique [0002] Usually, when rewriting an integrated chip, a special rewriter is required to rewrite the chip. This special rewriter stores a large amount of data. During the rewriting process, the rewriter writes the relevant data stored in it into the chip. , to make the chip recognizable and usable by the device. [0003] When rewriting data, the rewriter must first read the configuration information of the chip for analysis and comparison, and then rewrite the data on the corresponding address. However, the analysis and comparison function of configuration information will cause some chips that have been corrected to fail. was rewritten again. [0004] During the operation of the chip being rewritten, the rewriting may be interrupted or wrong data...
