Abstract
A non-volatile multi-bit storage device that includes a phase change material doped with n-type or p-type semiconductor impurities, a first set of electrodes ohmically coupled to the phase change material, a second set of electrodes configured to apply an electric field across the phase change material. To program the non-volatile multi-bit storage device, an electrical field is applied to the phase change material as crystal annealing cool down is performed. Application of the electric field during the crystal annealing cool down forms a rectified current path through the phase change material.
