Novel memory and several logic circuits utilizing the chaotic oscillations produced in SQUIDs are proposed. First, the oscillation modes that can be produced in a SQUID circuit are analyzed. The results of simulation for the SQUID show that there exist four types of oscillations: periodic, subharmonic, chaotic and relaxation oscillations. The bifurcation diagram of oscillation waveforms reveals that the hysteresis phenomena in the relation between the terminal voltage or the current and the external flux appear and that these phenomena can be used for a memory operation. Secondary, novel digital circuits such as memory, Exclusive-OR and full adder circuits are proposed by utilizing the chaotic oscillations. In these digital circuits the chaotic oscillations are made correspond to the logic "1," while the periodic and subharmonic oscillations are made to the logic "0". In order to investigate how these digital circuits perform their functions, computer simulations are made. The simulation results show that the right operations can be achieved.
