Abstract of the Disclosure

Disclosed is a memory system capable of being integrated into a semiconductor substrate and having an array of Hi-C memory cells. The Hi-C cells are selectively addressable by row and column lines. Each cell of the array is comprised of a transistor having a source coupled to a bit line, a gate couple to a word line and a drain coupled to a node N. Node N is coupled in parallel to a dielectric capacitor and to a depletion capacitor. The dielectric capacitor and the depletion capacitor are constructed to have substantially the same charge capacity.
