Abstract
A superconductor storage device and a memory constructed by arranging a plurality of superconductor storage devices are disclosed. The superconductor storage device is comprised of a word line, a write-in line, a first loop of superconductor composed of two branch paths of superconductor connected to the word line so as to allow a current flowing in the word line to be retained in the first loop, a weakly coupling portion inserted in at least one of the two branch paths, the weakly coupling portion being subject to the influence of a magnetic field generated by the write-in line to control the retention of the current in the first loop, and a second loop of normal conductor provided so as to be magnetically coupled with the first loop, the second loop including an input path and an output path which allow the application of a voltage to the second loop and two branch paths of normal conductor which makes a loop-wise connection between the input path and the output path.
