Shown on the left is theminimal Gaussian pulse amplitude for transition from 0 to 1 and on the right is theminimal pulse amplitude for transition from the 1 to 0 operation.We study memory states of a circuit consisting of a small inductively coupled Josephson junction array and introduce basic (write, read, and reset) memory operations logics of the circuit. The presented memory operation paradigm is fundamentally different from conventional single quantum flux operation logics. We calculate stability diagrams of the zero-voltage states and outline memory states of the circuit. We also calculate access times and access energies for basic memory operations.
