ABSTRACT:
Signal delivery delay margin of a bypass flip-flop circuit is stabilized during high-frequency operation. An input controller for logically operating a bypass signal and a clock produces first and second output signals having different states depending on whether or not the bypass signal is activated. A latch circuit latches input data based on the first and second output signals. A latch controller logically operates the bypass signal and input data to generate a third output signal having a different state depending on whether or not the bypass signal is activated. An output controller is switched in response to the states of the first and second output signals for logically combining an output signal selected from the latch circuit and the third output signal to provide the output signal.
