Abstract

PURPOSE:To contrive an increase in the degree of integration of a closed circuit by a method wherein a memory cell is provided with an inductance using a superconductive material, three-terminal type superconducting switching elements and the closed circuit constituted of a superconductive wiring material. CONSTITUTION:Three-terminal type superconducting switching elements 2, superconducting coils 1 and a closed circuit constituted of a superconductive material are used for a memory cell. That is, the elements 2 are turned-ON and a state that a circulating current is made to flow in the closed circuit brought into a superconductive state is assumed to be a storage state of 1 and a state that the current is not made to flow is assumed to be a storage state of 0. Accordingly, so long as an action is not given to the closed circuit from the exterior, this state is sustained semipermanently. Therefore, information is stored statically. Moreover, by controlling the circulating current by a minority of pieces of the elements 2 in the closed circuit, a writing and a readout can be performed. Thereby, the totaled occupation area of all the elements including the coils 1 can be reduced and the improvement of the integration degree of the closed circuit can be contrived.
