Abstract: Methods for programming memory cells of a resistive memory device include applying a voltage pulse sequence to a memory cell to set a logic state of the memory cell. An initial set sequence of voltage pulses may be applied to the memory cell, followed by a reform voltage pulse having an amplitude greater than the amplitudes of the initial set sequence, and within ±5% of the amplitude of a voltage pulse used in an initial forming process. Additional voltage pulses having amplitudes that are less than the amplitude of the reform voltage pulse may be subsequently applied. By applying a reform voltage pulse in the middle of, or at the end of, a memory set sequence including multiple voltage pulses, a resistive memory device may have a larger memory window and improved data retention relative to resistive memory devices programmed using conventional programming methods.
