STMicroelectronics Assigned Patent

STMicroelectronics (Crolles 2) SAS, Crolles, France, has been assigned a patent (11690303) developed by Berthelon, Remy, Saint Martin d’Heres, France, and Arnaud, Franck, St Nazaire les Eymes, France, for an “electronic chip with two phase change memories.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An electronic chip includes at least a first array of first elementary cells and a second array of second elementary cells. The first and second elementary cells form two types of phase change memory having a storage element formed by a volume of phase change material having either a crystalline state or an amorphous state depending on the bit stored. Each first elementary cell includes a volume of a first phase change material, and each second elementary cell includes a volume of a second phase change material that is different from the first material. Each elementary cell includes a heating connector configured for the passage of a heating current adapted to cause a phase change of the volume of phase change material of the elementary cell.”

The patent application was filed on 2021-03-29 (17/216193).
