Abstract
A memory device is provided. The memory device including memory cells having at least three stacked electrodes spaced apart pairwise by dielectric material so that the pairs of electrodes form respective capacitor layers. The capacitors are connected electrically in parallel to each other. The dielectric material is optionally ferroelectric material, in which case the capacitors are ferrocapacitors.
