ALEXANDRIA, Va., July 14 -- United States Patent no. 12,683,812, issued on July 14, was assigned to UNITED MICROELECTRONICS CORP. (Hsinchu, Taiwan).

"Physically unclonable function device and method for fabricating the same" was invented by Yang Tian (Singapore).

According to the abstract* released by the U.S. Patent & Trademark Office: "A PUF device includes a first transistor that has a first well with a first conductivity and a first channel region with a second conductivity, a second transistor that has a second well and a second channel region both with the first conductivity, and a reading circuit. When a gate-source voltage applied to these transistors is equal to 0, the first transistor and the second transistor are both in an off...
