ABSTRACT:
A new type of superconducting memory is described. The composition of superconducting ceramic material used in the memory has been altered in order to expedite the formation of non-superconducting regions formed of grain boundaries. Non-superconducting regions may also be formed of lattice defects. Magnetic flux is trapped within the non-superconducting regions (grain boundaries or lattice defects). Information can be stored in terms of whether or not magnetic flux is trapped.
