The invention provides a method for encoding and decoding an error correction code. First, raw data is received and then divided into a plurality of data segments. A plurality of short parities corresponding to the data segments is then generated according to a first generator polynomial. The short parities are then appended to the data segments to obtain a plurality of short codewords. The short codewords are then concatenated to obtain a code data. A long parity corresponding to the code data is then generated according to a second generator polynomial, wherein the first generator polynomial is a function of at least one minimum polynomial of the second generator polynomial. Finally, the long parity is then appended to the code data to obtain a long codeword as an error correction code corresponding to the raw data.
