A memory design in QCAs using the SQUARES formalism
D. Berzon, T. J. Fountain · 2003
We present a formalism for implementing circuits with quantum-dot cellular automata (QCA), comprising a set of standard circuit elements with uniform layout rules. The formalism simplifies circuit design from an engineering perspective and overcomes an observed sensitivity of QCA systems to input delays. A design for an addressable shift register is implemented, and promises considerable density gains over conventional CMOS.
