Abstract

A phase-change memory controller controls a phase-change memory device. The phase-change memory controller includes a write control circuit configured to receive first write data of 'N' bits (where “N” is a natural number greater than 2) to be written to the phase-change memory device to generate second write data composed of compressed data compressed with “M” bits (where “N” is a natural number smaller than “N”) and “0” padding data in which the rest “N-M” bits are filled with “0”.
