Classification: CPC H  G | IPC H

Claim 16:
17. A memory control circuit unit, used for controlling a rewritable non-volatile memory module, the memory control circuit unit comprising:
a host interface, used for coupling to the host system;
a memory interface, used for coupling to the rewritable non-volatile memory module a decoding circuit; and
a memory management circuit, coupled to the host interface, the memory interface, and the decoding circuit,
wherein the decoding circuit supports a plurality of decoding modes, the decoding modes respectively correspond to a threshold value, and a distribution of the threshold value corresponds to error correction abilities of the decoding modes,
the memory management circuit unit is used for:
sending a read command sequence, which instructs to read first data from the rewritable non-volatile memory module;
performing a first decoding operation on the first data by the decoding circuit;
obtaining a decoding parameter according to an execution result of the first decoding operation; and
instructing the decoding circuit to perform 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.
