ABSTRACT:
A method of transferring remanent polarization information from a photovoic ferroelectric unit to a polarizable unit which may either be another portion of the photovoltaic ferroelectric material or a separate piece of material. The photovoltaic ferroelectric unit is illuminated to produce a photovoltage and the voltage is applied to the unit to be polarized to induce the polarization. An optically addressable read-write photovoltaic ferroelectric memory plane having means for allowing writing and erasing of information by the transfer of remanent polarization from one portion of the memory plane to another.
