Abstract
It is made possible to provide a flip-flop circuit capable of implementing the error correction function with a small area increase as far as possible and a pipeline system using such a flip-flop circuit. A flip-flop circuit includes: a flip-flop configured to operate based on a rising edge or a falling edge of a first clock signal; a decision circuit configured to compare an input of the flip-flop with an output thereof and output a request signal when the input of the flip-flop is different from the output thereof; and a control circuit configured to receive a second clock signal from outside and generate the first clock signal and a confirmation signal. When the request signal is sent from the decision circuit after the flip-flop has been activated, the control circuit inverts the first clock signal, sends the confirmation to the decision circuit, and makes the decision circuit cancel the request signal.
