Abstract
An array of programmable non-volatile devices use a floating gate that functions as a FET gate that overlaps a portion of a common source/drain region. This allows a programming voltage for the device to be imparted to the floating gate through capacitive coupling, thus changing the state of the device. The invention can be used in environments such as data encryption, reference trimming, manufacturing ID, security ID, and many other applications.
