ABSTRACT:
A diode-forming layered structure comprising a semiconductor body having a layered coating thereon, said semiconductor having a surface region of given conductivity type, said coating being a dispersed metal particle-polymer coating which before electrical activation displays a high electrical resistance but after electrical activation is highly conductive, said electrical activation resulting in the formation of a diode in the zone of contact between the coating and the semiconductor body, a plurality of such layered structures, in a two-dimensional array based on a common semiconductor body, being useful in the formation of a read-only memory (ROM), an alterable read-only memory (AROM) or a random access memory (RAM).
