Recent advances in logic schemes and fabrication processes have renewed interest in using superconductor electronics for energy-efficient computing and quantum control processors. However, scalable superconducting memory still poses a challenge. To address this issue, this disclosure presents an alternative to approaches that solely emphasize storage cell miniaturization by exploiting the minimal attenuation and dispersion properties of superconducting transmission lines to develop a delay-line memory system. The fully superconducting design is operable at frequencies ranging from approximately 20 GHz to 100 GHz and achieves data densities on the order of tens to thousands of megabits per square centimeter. Additionally, the circulating nature of this design allows for minimal control circuitry, eliminates the need for data splitting and merging, and enables inexpensive implementations of sequential access and content-addressable memories.
