Embodiment Construction

[0044] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0045] The SRAM dead point processing method provided by this application can be applied to the bad point management unit of the chip, and the bad point management unit can be an independent control device, such as a bad point manager, or a functional module in the system chip. The bad point management unit may include an information register and a data register, and reads and writes the data content corresponding to the SRAM bad point address stored in the data register according to the access request of the CPU or other peripheral IP.

Abstract

The present application relates to the technical field of memory, and provides a SRAM bad point processing method, system, device, computer equipment and storage medium. The method includes: matching the access address for the SRAM obtained by receiving the data access module with the dead point address stored in the information register after the CPU scans, obtaining the target bad point address matched by the access address, and obtaining the target bad point address corresponding to the target bad point address The data register, from which the corresponding data content is read and written. In the solution provided by this application, the bad point addresses scanned by the CPU are stored in the information registers, and the corresponding data registers are configured for each bad point address in advance to store the data content corresponding to the bad point addresses, so that during the use of the SRAM, it can Dynamically manage the bad point of SRAM, realize the reading and writing of SRAM data content corresponding to the bad point address through the data register, realize the replacement operation of SRAM bad point, improve the efficiency of SRAM bad point management, and further improve the SRAM reliability.

Description

technical field [0001] The present application relates to the technical field of memory, in particular to a method, system, device, computer equipment and storage medium for processing SRAM bad points. Background technique [0002] Static Random-Access Memory (SRAM) is a type of random-access memory, which is widely used for chip cache. Failure of the address unit of SRAM will cause the entire SRAM to fail to work normally, thereby affecting the function of the chip. . Therefore, in the process of leaving the factory and using the chip, it is necessary to test the dead pixels of the SRAM. [0003] In the current technology, usually when the chip leaves the factory, the SRAM adopts the method of adding redundant columns and redundant rows to replace the dead pixels. The manufacturing process is complicated, and it is impossible to replace the dead pixels that appear during use. Contents of the invention [0004] Based on this, it is necessary to provide a SRAM dead point ...
