CEA Assigned Patent

Commisariat à l’Energie Atomique et aux Energies Alternatives (CEA), Paris, France, has been assigned a patent (11,444,040) developed by Charpin-Nicolle, Christelle, and Pebay-Peyroula, Florian, Grenoble, France, for “method for manufacturing a microelectronic device integrating a physical unclonable function provided by resistive memories, and said device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A microelectronic device and method for manufacturing a microelectronic device comprising a plurality of resistive memories, a part of these resistive memories, called PUF memories, forming a PUF, the rest of these resistive memories being known as storage memories. The manufacturing process comprising forming a dielectric layer having on at least one contact surface in contact with an electrode a surface roughness of said surface greater than that of the same dielectric layer of the storage memories.”

The patent application was filed on September 21, 2020 (17/027,193).
