Abstract

PURPOSE:To facilitate high integration and to provide optimum property for a logic and memory circuits, by coupling on nearly the same plain two quantum interference type closed loop thin film like including a Josephson junction in each antiparalleled magnetic flux quantum condition. CONSTITUTION:For instance, a micro-bridge type or a tunnel type Josephson element 3 is made by patterning of Pb alloy or conductive metals such as Sn, Nb (or by interposing a tunnel oxide film). For example, two closed circuits 2 are made by five elements 3, with one element 3 commonly owned. A circuit current supplying line 1 and a phase controlling line 4 are provided to control a current flow to make antiparalleled magnetic flux quantum condition to perform a logic operation or memory operation. This method makes possible, without providing a superconduction shield layer, the formation of high integration preventing interlayer interference, and construction of a high intensity and a high speed super condution circuit just by interposing an ordinary thin insulation film.
