The shifting cache includes a signal production circuit that produces the output signal at the fan-out of the shifting cache according to a clock signal when it is breakover; a driving circuit bimorph connect with the signal production circuit, which control the signal production circuit according to the receiving input signal from the output end of the shifting cache; a main resetting circuit bimorph connect with the signal production circuit, which use to cut the signal production circuit and reset the output signal from the output end; a reactive circuit signal bimorph connect with the output end and the main resetting circuit, which control the main resetting circuit according to the output signal and the clock signal.
