This specification describes semiconductor storage cells for use in monolithic memories. These cells each have two planar transistors formed on a single surface of a monolithic chip. The planar transistors are coupled together to form a bistable circuit and are supplied power from a voltage distribution layer of the chip under the planar transistors so that the load elements for the storage cells are formed vertically through the monolithic chip between the voltage distribution layer and the planar transistors.
