PURPOSE: A memory system and a control method for the same are provided to perform an LDPC decoding operation with high reliable data through one time processing operation. CONSTITUTION: A first ECC(Error-Correct Code) decoder(30) performs HDC(Hard Decision Code) decoding operation based on sector data, and a second ECC decoder(40) performs an LDPC(Low Density Parity Check) decoding operation based on frame data. A sector error flag section sets up a sector error flag which memorizes error data information of the HDC decoding operation. An ECC control section increases the reliability of sector data which do not include error data based on the information on the sector error flag section. |
