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 an increment of bit data identified as a first status among the verification bit data, obtaining a new read voltage value set based on the increment, 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 statuses of memory cells in the rewritable non-volatile memory module can be identified correctly, thereby preventing data stored in the memory cells from losing.
