*Abstract

A bistable electrical device that is convertible between a low resistance state and a high resistance state. The device includes at least one layer of organic low conductivity material that is sandwiched between two electrodes. A buffer layer is located between the organic layer and at least one of the electrodes. The buffer layer includes particles in the form of flakes or dots of a low conducting material or insulating material that are present in a sufficient amount to only partially cover the electrode surface. The presence of the buffer layer controls metal migration into the organic layer when voltage pulses are applied between the electrodes to convert the device back and forth between the low and high resistance states.
