Abstract
A decoding method, a memory storage device and a memory controlling circuit unit are provided. The decoding method includes: reading at least one memory cell according to a first read voltage to obtain at least one first verification bit; executing a hard bit mode decoding procedure according to the first verification bit, and determining whether a first valid codeword is generated by the hard bit mode decoding procedure; if the first valid codeword is not generated by the hard bit mode decoding procedure, obtaining storage information of the memory cell; deciding a voltage number according to the storage information; reading the memory cell according to second read voltages matching the voltage number to obtain second verification bits; and executing a soft bit mode decoding procedure according to the second verification bits. Accordingly, the speed of decoding is increased.
