Rheinisch-Westfälische Technische Hochschule Aachen Assigned Patent

Rheinisch-Westfälische Technische Hochschule (RWTH) Aachen, Aachen, Germany, has been assigned a patent (11817146) developed by Wei, Shuai, Wuttig, Matthias, Cheng, Yudong, Pries, Julian, and Lu, Xiaoling, Aachen, Germany, for a “phase-change memory.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A phase-change memory (10) for the non-volatile storage of binary contents stores the binary contents electrically and/or optically in a non-volatile manner by locally switching a material (18) between an amorphous and a crystalline phase. The state with respect to the electrical conductivity of the material (18) and/or the reflection properties of the material (18) determines the information content of the phase-change memory (10). A method for non-volatile storage of binary contents in a phase-change memory (10), which stores the binary contents electrically and/or optically in a non-volatile manner by locally switching a material (18) between an amorphous and a crystalline phase, whereby the state with respect to the electrical conductivity of the material (18) and/or the reflection properties of the material (18) determines the information content of the phase-change memory (10).”

The patent application was filed on 2020-04-21 (17/608172).
