Abstract
We demonstrated a paradigm for cryogenic memory operation and presented a specific example of a circuit that consists of three inductively coupled Josephson junctions. We have employed Josephson junction parameter values that are consistent with the current state-of-the-art Josephson junction fabrication capabilities. For parameter values presented in the paper, memory cell access times are of the order of 10 - 100 ps while access energies are of the order of 0.1 – 5 aJ. The principles of memory cell design and operation described in our papers can in principle be implemented on other Josephson junction based circuits as well.
