Toshiba Global Commerce Solutions Assigned Patent

Toshiba Global Commerce Solutions, Inc., Durham, NC, has been assigned a patent (12290011) developed by Crockett; Timothy, Raleigh, NC, and Bartus, Jr.; Lester, Wake Forest, NC, for a “multi-bit storage device using phase change material.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “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.”

The patent application was filed on 2024-05-02 (18/653418).
