Abstract

A data holding characteristic of a memory cell is improved in a memory system in which data is encoded and written to a memory cell.A first candidate parity generation unit generates, as a first candidate parity, a parity for detecting an error in an information section in which a predetermined value is assigned in a predetermined variable area. A second candidate parity generation unit generates, as a second candidate parity, a parity for detecting an error in the information section in which a value different from the predetermined value is assigned in the predetermined variable area. A selection unit selects a parity that satisfies a predetermined condition from among the first and second candidate parities as a selection parity. An output unit outputs a codeword constituted by the information section corresponding to the selection parity and the selection parity.
