This abstract first appeared for US patent application 18984230 titled 'PUF CELL ARRAY, SYSTEM AND METHOD OF MANUFACTURING SAME

Original Abstract Submitted

A physically unclonable function (PUF) cell array includes a first PUF cell in a first column in a first direction, and a second PUF cell in a second column. The first PUF cell includes a first set of conductive structures that include a first conductive structure extending in the second direction and a second conductive structure extending in the first direction. The second PUF cell includes a second set of conductive structures that include a third conductive structure extending in the second direction and a fourth conductive structure extending in the first direction. At least the first and third conductive structure, or the second and the fourth conductive structure are symmetric to each other with respect to a central line between the first or second PUF cell.
