Crocus Technology Assigned Patent

Crocus Technology SA, Grenoble, France, has been assigned a patent (10,157,652) developed by Stainer, Quentin, Montbonnot-St-Martin, France, for a “magnetic device configured to perform an analog adder circuit function and method for operating such magnetic device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A magnetic device configured to perform an analog adder circuit function and including a plurality of magnetic units. Each magnetic unit includes n magnetic tunnel junctions electrically connected in series via a current line. Each magnetic tunnel junction includes a storage magnetic layer having a storage magnetization, a sense magnetic layer having a sense magnetization, and a tunnel barrier layer. Each magnetic unit also includes n input lines, each being configured to generate a magnetic field adapted for varying a direction of the sense magnetization and a resistance of the n magnetic tunnel junctions, based on an input. Each of the n magnetic units is configured to add said n inputs to generate an output signal that varies in response to the n resistances.”

The patent application was filed on May 31, 2016 (15/578,841).
