Abstract:
A method for reading data from a block of a flash memory is provided, where the block includes a plurality of pages and at least one parity page, each of the pages includes a plurality of sectors used for storing data and associated row parities, each of the sectors of the parity page is used to store a column parity. The method includes: reading data from a specific page of the pages; decoding the data of the specific page; and when a specific sector of the specific page fails to be decoded, sequentially reading all original data of the pages and the parity page, and performing error correction upon the specific sector according to at least a portion of the original data of the pages and the parity page corresponding to the specific sector.
