Tohoku University and National Institutes for Quantum Science and Technology Assigned Patent

Tohoku University, Miyagi, Japan and National Institutes for Quantum Science and Technology, Chiba, Japan, has been assigned a patent (12159668) developed by Mizukami; Shigemi, Fukami; Shunsuke, Nitta; Junsaku, Iihama; Satoshi, Hirayama; Yoshiro, Sendai, Japan and Sakai; Seiji, Chiba, Japan, for a “magneto-Optical Memory Interface.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A magneto-optical memory interface includes: a memory cell structure having multiple allocated magnetic recording cells, a selection means configured to select an individual or a predetermined number of the multiple allocated magnetic recording cells of the memory structure, and configured for an electronic signal to be applicable thereto; and a light irradiation part configured to irradiate the predetermined number of the multiple allocated magnetic memory cells with an optical signal, wherein each of the magnetic recording cells is a magnetic recording cell whose sensitivity to changes in a magnetization state thereof increases in response to an irradiation light from the light irradiation part, and each of the magnetic recording cells is a magnetic recording cell whose magnetization state changes in response to an applied electrical signal resulting from selection by the selection means and the irradiation light from the light irradiation part.”

The patent application was filed on 2020-09-30 (18/246780).
