Abstract
Methods and apparatus for providing an antifuse are disclosed, where the antifuse includes a semiconductor substrate having an active area circumscribed by a shallow trench isolation (STI) boundary; a gate conductor disposed above the semiconductor substrate and overlying at least a portion of the STI boundary; a dielectric disposed between the semiconductor substrate and the gate conductor; a first terminal coupled to the gate conductor; and a second terminal coupled to the semiconductor substrate, wherein a breakdown of the dielectric causes electrical connections between regions of the gate conductor and regions of the active area including substantially near the STI boundary.
