Abstract

The embodiment of the invention discloses a method and a device for detecting error check and correcting memory, which relate to the technology of memory and can detect whether the ECC (Error Correction Code) function in the memory is in failure. The method comprises the following steps: writing detection data to the memory of processing data; reading the error check and correcting the error check in the memory and corrected check sum; judging whether the relationship between the detected data with the error check and corrected check sum satisfies the error check and corrected encryption algorithm; and if the relationship between the detected data with the error check and corrected check sum does not satisfy the error check and the corrected encryption algorithm, sending an error message for indicating the error check and correcting the error in the memory. The method and the device are mainly applied to detecting an ECC memory.

Description

technical field [0001] The present invention relates to memory technology, and more particularly to methods and devices for detecting error checking and correcting memory. Background technique [0002] For various processing systems, memory is essential, for example, PCs, laptops, servers, data communication equipment, and processor systems of some consumer products. Memory capacity, access speed and stability are the evaluation An important indicator of processor system performance. [0003] In a processor system, the Error Check & Correct (ECC, Error Check & Correct) function is one of the important functions to ensure data reliability. [0004] In communication systems, RAM (random access memory, random access memory) is widely used, and with the continuous improvement of people's demand for data transmission bandwidth, the memory capacity and speed requirements of communication systems are becoming larger and larger. faster. Correspondingly, a larger storage capacity ...
