Abstract

PURPOSE:To increase the scale of integration of an integrated circuit, make the protection from high voltage perfect even if gate oxide film is thinned and incrase the speed of system, by connecting inputs and outputs to the semiconductor integrated circuit through separately provided input/output protection circuits.
