SK hynix and Industry-University Cooperation Foundation Hanyang University ERICA Campus Assigned Patent

SK hynix Inc., Icheon, Korea, and Industry-University Cooperation Foundation Hanyang University ERICA Campus, Ansan, Korea, has been assigned a patent (11830549) developed by Ha, Tae Jung, Guri, Korea, Kim, Soo Gil, Yongin, Korea, Song, Jeong Hwan, Seongnam, Korea, Park, Tae Joo, Ansan, Korea, Seok, Tae Jun, Yongin, Korea, Kim, Hye Rim, Dongducheon, Korea, and Choi, Hyun Seung, Geoje, Korea, for “method of operating selector device, method of operating nonvolatile memory apparatus applying the same, electronic circuit device including selector device, and nonvolatile memory apparatus.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Disclosed are a method of operating a selector device, a method of operating a nonvolatile memory apparatus to which the selector device is applied, an electronic circuit device including the selector device, and a nonvolatile memory apparatus. The method of operating the selector device controls access to a memory element, and includes providing the selector device including a switching layer and first and second electrodes disposed on both surfaces of the switching layer, which includes an insulator and a metal element, and applying a multi-step voltage pulse to the switching layer via the first and second electrodes to adjust a threshold voltage of the selector device, the multi-step voltage pulse including a threshold voltage control pulse and an operating voltage pulse. The operating voltage pulse has a magnitude for turning on the selector device, and the threshold voltage control pulse has a lower magnitude lower than the operating voltage pulse.”

The patent application was filed on 2022-06-30 (17/855424).
