Problems solved by technology

However, EFUSE itself will also have defects in the manufacturing process, burning process and use process, which will damage the data stored in it.
Existing solutions are mainly to replace defective units by adding redundant units, which can only solve the defects generated during the manufacturing and burning process, and cannot detect and repair the defects that occur during use

Abstract

The embodiment of the invention provides a data verification method and a circuit, and belongs to the technical field of computers. The method comprises the following steps: reading a data block and acheck code of the data block; according to the address of each bit in the data block in the data block, each bit of the data block is sequentially mapped to an n-dimensional space, the data length kof each dimension is the same, and n and k are positive integers; checking the data block according to the data block mapped to the n-dimensional space and the check code so as to judge whether an error bit exists in the data block; and outputting the address of the error bit in the data block when the error bit exists. According to the method, multiple rows of data in the EFUSE can be protected,and the coding efficiency is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and more particularly, to a data verification method and circuit. Background technique [0002] With the development of integrated circuits, the integration degree of chips and the complexity of circuits are constantly improving, which also brings greater challenges to the design and production of chips. In order to improve the yield of the manufacturing process, it is necessary to repair or close the manufacturing defect part of the chip, and record the corresponding information in the chip during the production process. Some analog designs in the chip need to be tested and configured with different parameters during the production process, and the corresponding configuration information also needs to be recorded in the chip. With the increasing complexity of chip design and the increasing diversification of requirements, in the process of chip production and subsequent use, various ...
