Query: Josephson thermal memory   We propose a superconducting thermal memory device that exploits the thermal
hysteresis in a flux-controlled, temperature-biased superconducting
quantum-interference device (SQUID). This system reveals a flux-controllable
temperature bistability, which can be used to define two well-distinguishable
thermal logic states. We discuss a suitable writing-reading procedure for these
memory states. The time of the memory writing operation is expected to be on
the order of ~0.2 ns, for a Nb-based SQUID in thermal contact with a phonon
bath at 4:2 K. We suggest a non-invasive readout scheme for the memory states
based on the measurement of the effective resonance frequency of a tank circuit
inductively coupled to the SQUID. The proposed device paves the way for a
practical implementation of thermal logic and computation. The advantage of
this proposal is that it represents also an example of harvesting thermal
energy in superconducting circuits.
