SUPERCONDUCTING MEMORY CELL AND SUPERCONDUCTING MEMORY DEVICE USING THE CELL

摘要

PROBLEM TO BE SOLVED: To lighten the burden on peripheral circuits by making a superconducting memory cell compact and highly speedily operable. SOLUTION: A first signal path X (X-) piercing a Josephson junction JJ in series is connected to a superconducting closed loop being constitution elements of an AC magnetic fluxes quantum interference device including an inductor Lo and a Josephson junction JJ in series, such relation is made that the inductor Lo and the Josephson junction JJ are connected in parallel and they are connected to the first signal line in series. The inductor Lo is provided with a second signal line Y (Y-) coupling magnetically through an inductor Ly.
