Patent 11355517 was granted and assigned to Ceremorphic on June, 2022 by the United States Patent and Trademark Office.
An AND or OR logic device has multiple layers of ferromagnetic material separated from each other by non-magnetic layers of electrically conductive material of atomic thickness, sufficient to generate anti-magnetic response in a magnetized layer. The anti-magnetic response in a layer below a layer magnetized with a polarity is summed in a region which is coupled to an output, the output generating at least one of a AND or OR logic function on applied input magnetization.
