Abstract

A coated, 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, 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, and a protective layer covering the plurality of electrode traces and extending laterally beyond each edge of each electrode trace to provide a buffer zone surrounding each electrode trace, the buffer zone extending from an end of each electrode trace to cover a portion of each associated contact pad in an overlapping region, wherein each contact pad also has at least one uncovered edge.
