Abstract
A design structure embodied in a machine readable medium used in a design process includes an apparatus for sensing the state of a programmable resistive memory element device, the apparatus further including a latch device coupled to a fuse node and a reference node, the fuse node included within a fuse leg and the reference node configured within a reference resistance leg, the latch device configured to detect a differential signal developed between the reference node and the fuse node as the result of sense current passed through the fuse leg and the reference resistance leg; and the fuse and reference resistance legs further configured for first and second sensing modes, wherein the second sensing mode utilizes a different level of current than the first sensing mode.
