ABSTRACT:
A superconducting fault-tolerant programmable read-only memory (SFT-PROM) cell stores information in the phases of superconducting wires in a Josephson array. The information is addressable and retrievable in a fault-tolerant manner due to the non local nature of the information stored. The coding and decoding process is content-addressable and parallel due to the multitude of interconnections, resulting in picosecond data access time. The SFT-PROM cell comprises superposed WRITE/READ arrays and a reset circuit that ensures multiple non-destructive read-out of data.
