Abstract
A memory device, based upon a field effect transistor having a floating gate is constructed for use in a silicon integrated circuit array of similar memory devices. The memory device includes only two polysilicon layers, a portion of each polysilicon layer being connected to each other through a via hole in an intervening silicon dioxide layer to form the floating gate.
