A logic system includes first and second identical logic circuit building blocks, each referred to as an M Circuit, which responds to transitions of a two level, binary input signal to provide a memory and a logic function which has a complete truth table for every possible combination of input signal transitions or changes in logic level at a pair of input terminals A and B. Each of the M Circuits includes gates having two inputs connected to the A and B input terminals, respectively and a set-reset flip flop having its set input connected to the output of the gate, its reset input connected to the B input terminal and its set and reset outputs connected respectively to output terminals Q and Q of the M Circuit, with the Q and Q output terminals providing complementary binary outputs for any combination of binary inputs applied at the A and B input terminals, providing a four terminal device which responds to each transition of said input signal at the A and B terminals to provide outputs at the Q and Q terminals in accordance with its truth table functions. One of the Q and Q output terminals of the first M Circuit is connected with one of the A and B input terminals of the second M Circuit.
