You are about to enter the World of RSFQ -- one of the most exciting, most unusual and most promising superconductor technologies of the Tomorrow. RSFQ stands for Rapid Single-Flux-Quantum Logic/Memory Family.
RAPID
Typical speed of RSFQ devices fabricated using an obsolete 3.5um technology is close to 100GHz (20GHz clock). The ultimate speed of an RSFQ device ever measured experimentally is 770GHz.
SINGLE-FLUX-QUANTUM
In RSFQ, information is stored in superconductor loops as tiny magnetic flux quanta and transferred as several picosecond-wide voltage spikes with quantized area. The tiny and quantized nature of magnetic flux quanta significantly (by several orders of magnitude) reduces crosstalk and power consumption, as compared to CMOS devices.
LOGIC/MEMORY
There are no combinational RSFQ gates in the traditional understanding of this word. Most of RSFQ elementary cells combine logic functions and storage capacities, acting as "smart" flip-flops and giving designers a plenty of unique opportunities.
FAMILY
There are almost 30 elementary cells available for an RSFQ digital designer. Among them: transmission lines, splitters, mergers, memory cells, flip-flops, inverters, logical cells (AND, OR, XOR), converters...
