Abstract
A semiconductor device is provided. The semiconductor device includes a metal-oxide-semiconductor field-effect-transistor (MOSFET) device electrically attachable to a first data line and a read-only memory (ROM) element. The ROM element is electrically interposable between the MOSFET device and a second data line. The ROM element includes first and second sets of memory cells in high and low resistance states, respectively, to form a secure identifier (ID).
