A barcode decoding method includes steps of (a) capturing an image of a barcode; (b) analyzing the image to recognize a data region of the barcode; (c) decoding the data region to obtain a codeword matrix, wherein the codeword matrix includes a plurality of codewords; (d) performing an error correction for the codeword matrix; (e) when the codeword matrix fails to pass the error correction, repeating steps (a) to (c), updating the codeword matrix according to a number of occurrence times of each codeword at an identical position of the codeword matrix, and repeating step (d) for the codeword matrix after updating; and (f) when the codeword matrix passes the error correction, decoding the codeword matrix.

To prevent memory cells from being damaged, the present invention provides a data storage method for an electronic device, which comprises dividing a first section of a memory of the electronic device into N blocks, wherein each of the N blocks is corresponding to a sequence number and assigned an index value; rewriting an assigned index value corresponding to an nth block of the N blocks according to index values corresponding to the N blocks; storing an input data in the nth block; and rewriting the nth block by stored data in the (n&#x2212;1)th block before storing the input data in the nth block when the index values corresponding to the N blocks are not identical such that a number of times of accessing sections of the memory is averaged, to prevent the memory from being damaged; wherein N is an integer greater than or equal to 1, and 1&#x2266;n&#x2266;N.
