Basic circuits for multi-valued sequential logic

Multi-valued logic circuits have been offered as a solution to general interconnection and chip area problem. It has the potential of reducing the number of active elements and interconnection lines. More data may be transferred trough a single wire using logic signals having more than two levels. This technology leads to a decrease in number of interconnections and resistance and capacitance of contacts and interconnections. However, in spite of their potential advantages, developments in multivalued systems are not satisfactory. In particular, it is very difficult to find circuits to implement the multilevel sequential circuits. In this paper we present a new latch and restoration circuit which improves the performance of the previously designed flip-flop circuit. The flip-flop is the basic building block of multilevel sequential circuits and may be used to design sequential circuits such as multilevel counter/dividers and other sequential circuits.
