Data reading method, storage controller and storage device for optimizing read voltages
A data reading method is provided. The method includes using X read voltage sets to read a target word line, so as to obtain X read results; in a first order, updating a final Gray code index of each of a plurality of target memory cells of the target word line, and obtaining (X−1) abnormal Gray code count sets according to the X read results, wherein an ith read result among the X read results includes a Gray code corresponding to an ith read voltage set of each of the target memory cells, and the Gray code corresponds to one of N Gray code indexes; and selecting (N−1) optimized read voltages from (X−1)*(N−1) read voltages of the corresponding (X−1) read voltage sets to form an optimized read voltage set according to the obtained (X−1) abnormal Gray code count sets.
