Inventor: Shih-Jia Zeng , Yi-Fang Chang , Chun-Wei Tsao , Chen-An Hsu , Wei Lin
CPC classification number: H03M13/1555 , H03M13/015 , H03M13/1575
Abstract: A decoding method, a memory storage device and a memory control circuit unit are disclosed. The method includes: activating a decoding circuit which supports a plurality of decoding modes each corresponding to a threshold value, wherein a distribution of the threshold value corresponds to error correction abilities of the decoding modes; reading first data from a rewritable non-volatile memory module; performing, by the decoding circuit, a first decoding operation on the first data; obtaining a decoding parameter according to an execution result of the first decoding operation; and performing, by the decoding circuit, a second decoding operation on the first data based on a first decoding mode among the decoding modes according to a relative numerical relationship between the decoding parameter and the threshold value.
