Abstract: PURPOSE:To enable the pitch arrangement of memory cells to be shortened to a value restricted by the processing limit by a method wherein the titled device is constructed by including junction breakdown type memory cells formed in such a manner that the write voltage becomes less than the source voltage of the internal circuit. CONSTITUTION:An N<+> type buried collector layer 12 is provided to a P<-> type Si substrate 11, and an N<-> type epitaxial layer serving as a collector region 13 is formed thereon.
