Experimental single flux quantum NDRO Josephson memory cell |
| |
Abstract: | Single flux quantum nondestructive readout (NDRO) Josephson memory cells which store an energy of only ~6/spl times/10/SUP -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 /spl mu/m technology. |
