Abstract
A decoding method, a memory storage device and a memory controlling circuit unit are provided. First, memory cells are read to obtain verification bits. A first hard bit mode decoding procedure is performed according to the verification bits and whether the first hard bit mode decoding procedure generates a first valid codeword is determined by a first correcting circuit. If the first valid codeword is generated, the first valid codeword is outputted. If the first valid codeword is not generated, a second hard bit mode decoding procedure is performed, and whether the second hard bit mode decoding procedure generates a second valid codeword is determined by a second correcting circuit. A precision of the first correcting circuit is less than a precision of the second correcting circuit. Accordingly, the speed of decoding is increased.
