    Abstract: An error processing method for a rewritable non-volatile memory module, a memory storage device and a memory controlling circuit unit are provided. The rewritable non-volatile memory module includes a plurality of memory cells. The error processing method includes: sending a first read command sequence for reading a plurality of bits from the memory cells; performing a first decoding on the bits; determining whether each error belongs to a first type error or a second type error if the bits have at least one error; recording related information of a first error in the at least one error if the first error belongs to the first type error; and not recording the related information of the first error if the first error belongs to the second type error. Accordingly, errors with particular type may be processed suitably.

    Abstract: A data reading method for a rewritable non-volatile memory module is provided. The method includes applying a test voltage to a word line of the rewritable non-volatile memory module to read a plurality of verification bit data. The method also includes calculating a variation of bit data identified as a first status among the verification bit data, obtaining a new read voltage value set based on the variation, and updating a threshold voltage set for the word line with the new read voltage value set. The method further includes using the updated threshold voltage set to read data from a physical page formed by memory cells connected to the word line. Accordingly, storage states of memory cells in the rewritable non-volatile memory module can be identified correctly, thereby preventing data stored in the memory cells from losing.
