US Patent Issued to UNM RAINFOREST INNOVATIONS on Dec. 30 for "Systems and methods for analyzing stability using metal resistance variations" (New Mexico Inventor)

ALEXANDRIA, Va., Dec. 31 -- United States Patent no. 12,511,104, issued on Dec. 30, was assigned to UNM RAINFOREST INNOVATIONS (Albuquerque, N.M.).

"Systems and methods for analyzing stability using metal resistance variations" was invented by James Plusquellic (Albuquerque, N.M.).

According to the abstract* released by the U.S. Patent & Trademark Office: "This disclosure describes techniques for analyzing statistical quality of bitstrings produced by a physical unclonable function (PUF). The PUF leverages resistance variations in the power grid wires of an integrated circuit. Temperature and voltage stability of the bitstrings are analyzed. The disclosure also describes converting a voltage drop into a digital code, wherein the conversio...
