Superconducting memory is an essential requirement for integrated high–density superconducting digital electronics. Josephson junctions based memory cells have a high clock–speed and a very small power dissipation. Limited by the size of a flux quanta and thereof required inductancies, such elements are difficult to scale to small dimensions. In this presentations, we introduce a new superconducting memory concept, which potentially allows a large integration density.
