In information theory and coding theory with applications in computer science and telecommunication, error detection and correction or error control are techniques that enable reliable delivery of digital data over unreliable communication channels. Many communication channels are subject to channel noise, and thus errors may be introduced during transmission from the source to a receiver. Error detection techniques allow detecting such errors, while error correction enables reconstruction of the original data in many cases.
A data access method, a memory controller, an electronic device, and a medium
This disclosure provides a data access method, a memory controller, an electronic device, and a medium, relating to the field of chip technology. It includes: determining a first storage region in a memory cell of a dynamic random access memory (DRAM), the first storage region being used to store error detection and correction (ECC) data; responding to write command information corresponding to an access request, determining first ECC data corresponding to the write command information, the first ECC data being used to verify the write data corresponding to the write command information; storing the write data corresponding to the write command information and the first ECC data in the same first memory cell, the first ECC data being stored in the first storage region within the first memory cell. The method proposed in this disclosure, while ensuring data integrity, significantly reduces space overhead, row activation latency, and bandwidth usage, improving the effective bandwidth and access efficiency of DRAM.
