DATA CODING METHOD, DATA DECODING METHOD, ERROR CORRECTION METHOD, MEMORY CONTROLLER, CHIP, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/124709
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a data coding method, a data decoding method, an error correction method, a memory controller, a chip, and a device. The coding method comprises: determining data to be written into a memory, and mapping said data into multiple data symbols; coding the multiple data symbols according to an extended coding matrix to obtain multiple check symbols, wherein the extended coding matrix is obtained on the basis of deformation of a standard coding matrix, the extended coding matrix does not have same column vectors under a symbol of a target data size, and the column vectors in the extended coding matrix are different from unit column vectors in a unit matrix corresponding to the check symbols; and writing the multiple data symbols and the multiple check symbols as a coding result into the memory, wherein the multiple check symbols are used for performing error correction on the coding result when the coding result is read from the memory. The embodiments of the present disclosure can improve the degree of coverage of data symbols by check symbols, and provide support for increasing the number of symbols that can be corrected by an error correction algorithm, thereby improving the error correction capability.
