Abstract :
A new type of double-rank sequential circuit is presented in this paper. This new type, called Type 4, differs from its predecessor types in that it employs a Boolean memory as rank-1 memory instead of flip-flops. The Boolean memory used is an aggregate of symmetric Boolean memories with 1-out-of-n state encodings. A procedure for realizing a sequential machine by a Type 4 double-rank sequential circuit is also presented in the paper.
