A printed electronic device may comprise a plurality of contact pads arranged in a pattern, a plurality of electrode traces arranged in another pattern, the plurality of electrode traces comprising a set of bottom electrode traces and a set of top electrode traces, each electrode trace in electrical communication with an associated contact pad of the plurality of contact pads, and a plurality of memory cells, each memory cell located at an intersection of a pair of electrode traces of the plurality of electrode traces and comprising a bottom electrode layer formed from a region of one of the bottom electrode traces, a top electrode layer formed from a region of one of the top electrode traces, and a ferroelectric layer between the bottom and top electrode layers. The plurality of contact pads comprises at least one unmodified contact pad having a surface area, shape and size, the plurality of contact pads further comprising at least one modified contact pad having a reduced surface area, and a different size, a different shape, or both, as compared to the at least one unmodified contact pad.
