Abstract
A decoding parameter updating method, a memory storage device, and a memory control circuit unit are provided. The method includes: sending a read command sequence to a rewritable non-volatile memory module to instruct to read first data from a first physical unit based on multiple read voltage levels; decoding the first data according to multiple decoding parameters to obtain second data, wherein the decoding parameters respectively correspond to multiple voltage intervals, and the voltage intervals are defined by the read voltage levels; obtaining first error evaluation information corresponding to a first voltage interval among the voltage intervals according to the first data and the second data; and updating a first decoding parameter corresponding to the first voltage interval according to the first error evaluation information.
