Abstract

See full text

A superconducting switching circuit comprises a DCFP circuit composed of two Josephson junction elements constituting two current paths, respectively. Each of the current paths includes a resistor for suppressing resonance. A memory cell constituted by the DCFP circuit includes three Josephson junction elements constituting three current paths, respectively. Each of the current paths includes a resistor for suppressing resonance. A memory circuit comprises a number of memory cells of such a structure.
