Digital computer having control and arithmetic sections stacked above semiconductor substrate

摘要

Disclosed is a digital computer having memory means stacked on an insulating layer over a semiconductor substrate. In one embodiment, the memory means includes an array of diodes which overflies the substrate and generates control signals for an arithmetic section that lies in the substrate; and in another embodiment, the memory means includes N arrays of diodes which overlie the substrate and operate in parallel to generate signals representing arithmetic transformation of a portion of their address inputs.
