发明名称 High density programmable read-only memory employing double-wall spacers
摘要 The present invention provides an EPROM and a method for forming the same having increased density. The invention does so by reducing the area required for formation of a contact. Specifically, a storage cell for an electrically programmable read-only memory having a pair of spaced-apart gate structures, with a double wall spacer structure disposed on opposite sides of each gate structure.
