Decoding method, memory controlling circuit unit, and memory storage device

摘要

The present invention provides a decoding method, a memory controlling circuit unit, and a memory storage device. The decoding method includes: receiving a plurality of commands; reading a first physical programming unit to obtain a plurality of first data respectively by using a plurality of first reading voltage groups of a plurality of reading voltage groups based on a first read command of the plurality of commands and executing a first decoding operation in each of the plurality of first data, wherein a number of the plurality of first reading voltage groups is less than a number of the plurality of reading voltage groups; and executing other commands being different from the first read command of the plurality of commands when unsuccessfully executing the first decoding operation for each of the plurality of first data.
