Zusammenfassung:Superconducting switch having a persistent and a non-persistent state and its use as a driver in a memory system are described. An example superconducting switch includes a first superconducting layer and a second superconducting layer. The superconducting switch includes a first magnetic layer having a fixed magnetization state. The superconducting switch includes a second magnetic layer capable of being at least in a first or a second magnetization state. The superconducting switch is capable of being in a first state or a second state, and the superconducting switch is configured such that an application of a magnetic field to the second magnetic layer changes a magnetization of the second magnetic layer from the first magnetization state to the second magnetization state placing the superconducting switch in the second state and a removal of the magnetic field automatically returns the superconducting switch from the second state to the first state.
