ABSTRACT:
A read only memory device includes a first electrode and a second electrode arranged in an overlapping relation with the first electrode so as to be geometrically in connection at an intersection therewith corresponding to a storage location for one type of data. At least one of the first and second electrodes is formed of a ceramics system high temperature superconductor. A prescribed one of the two electrodes which is formed of the high temperature superconductor has a high resistance region for insulating the first and second electrodes from each other at an intersection corresponding to a storage location for another type of stored data. The high resistance region is formed by irradiating an intersection with a focused ion beam.
