Abstract
A decoding parameter updating method, a memory storage device, and a memory control circuit unit are disclosed. The method includes the following. A reading command sequence is sent to a rewritable non-volatile memory module to instruct reading of first data from a first physical unit based on multiple read voltage levels. A logical operation is performed on a first data group to obtain decoding index information corresponding to the first data group. The first data group includes the first data and second data read from a second physical unit. Error evaluation information corresponding to a first voltage interval among multiple voltage intervals is obtained according to the first data and the decoding index information. A first decoding parameter corresponding to the first voltage interval is updated according to the error evaluation information.
