Abstract
An electrically programmable read only memory (EPROM) of the floating gate type is constructed having an improved coupling ratio made by allowing the edges of the floating gates to be self aligned with the edges of the control gates. The ratio of the capacitance between the floating gate and control gate is increased by extending the floating gate out over the source and drain.
