Abstract
The present invention provides structures for antifuses that utilize electromigration for programming. By providing a portion of antifuse link with high resistance without conducting material and then by inducing electromigration of the conducting material into the antifuse link, the resistance of the antifuse structure is changed. By providing a terminal on the antifuse link, the change in the electrical properties of the antifuse link is detected and sensed. Also disclosed are an integrated antifuse with a built-in sensing device and a two dimensional array of integrated antifuses that can share programming transistors and sensing circuitry.
