Experimental Single Flux Quantum NDRO Josephson Memory Cell

Abstract

Single flux quantum NDRO Josephson memory cells which store an energy of only ·- 6 × 10–20 J have been successfully fabricated and operated for the first time. Margin enhancement due to quantization, and low operating currents render this cell an attractive basis for a < 1 ns access-time Josephson cache memory designed with a 2.5 µm technology.
