While the information industry keeps progressing with the rapid development of integrated circuit speedexceeding Moore’s Law, size and power consumption has become the key factor limiting further development ofIC due to the continuous improvement of its integration and complexity. Compared with binary circuits, multi-valued logic circuits have the advantage of higher information density, which provides an effective way to reducechip interconnector and area.
