Problems solved by technology

Based on this, in the data storage method of the above-mentioned high-bandwidth memory, when there are multiple errors in one DRAM in the high-bandwidth memory, there will be a situation where multiple errors are all corresponding to one check code. In this case, If the number of erroneous bits in the check code is greater than the number of bits that can be corrected by the check code itself, the check code cannot be corrected, thereby reducing the error correction rate of the data to be stored and reducing the storage cost of the data to be stored. reliability

Abstract

The invention relates to the technical field of computers, in particular to a data storage method and device, a storage medium and electronic equipment. The method comprises the following steps: determining the number of check codes, the number of bits of each check code, the number of storage chips and the number of interfaces on each storage chip according to the number of bits of to-be-stored data and a check mode; each check code is divided into a plurality of sub check codes, and the number of the sub check codes of each check code is the same as that of the storage chips; and respectively storing each sub check code of each check code into the different storage chips through the interface on each storage chip in a manner of respectively storing each sub check code of one check code into the different storage chips. The reliability of data storage is improved, and the storage steps are simple and easy to execute.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a data storage method and device, a storage medium, and electronic equipment. Background technique [0002] High Bandwidth Memory (HBM) is a high-performance DRAM (Dynamic Random Access Memory, Dynamic Random Access Memory) based on a 3D stack process initiated by AMD and SK Hynix. The high-bandwidth memory includes multiple DRAMs, wherein the number and specifications of the DRAMs are set according to specific situations. [0003] When storing the data to be stored in the DRAM in the high-bandwidth memory, first combine the verification method such as the SEC-DED Hamming code verification method or the DEC-TED-BCH code verification method to encode the data to be stored to obtain multiple verification methods. Check codes, and then store each check code in the DRAM in the high-bandwidth memory. [0004] However, since the number of erroneous bits that can be cor...
