Single flux-quantum Josephson memory cell using a new threshold characteristic
Journal Article
·
· Appl. Phys. Lett.; (United States)
A new single flux-quantum Josephson memory cell in which nondestructive readout (NDRO) operations can be realized with a simple circuit configuration is proposed. The memory cell utilizes a new type of threshold characteristics in an equivalent asymmetric dc superconducting quantum interference device (SQUID) consisting of a three-junction SQUID gate and a single junction. NDRO operation has been successfully demonstrated in an experimental memory circuit.
