Abstract

Phase-change memory devices are provided that include a plurality of phase-change memory cells and a reset pulse generation circuit configured to output a plurality of sequential reset pulses. Each sequential reset pulse is output to a corresponding one of a plurality of reset lines. A plurality of write driver circuits are coupled to corresponding phase change memory cells and to a corresponding one of the reset lines of the reset pulse generation circuit. Methods of programming phase-change memory devices using sequential reset control signals are also provided.
