description A method of programming a phase-change material. The method includes providing a transformation pulse to the phase-change material, where the transformation pulse includes a programming waveform and a conditioning waveform. The programming waveform provides sufficient energy to alter the structural state of the phase-change material. In one embodiment, the programming waveform alters the volume fractions of crystalline and amorphous phase regions within the phase-change material. The conditioning waveform provides sufficient energy to heat the phase-change material to a temperature above the ambient temperature but below the crystallization temperature of the phase-change material. The method programs the phase-change material to a state that exhibits a reduced time variation of resistance.
