Abstract
A flip-flop circuit includes first and second logic gates, a first selection circuit and a latch circuit. The first logic gate executes a logic operation on a first data signal and a first control signal. The second logic gate executes a logic operation on a second data signal and the first control signal. The operation results of the first and second logic gates are forcibly fixed to a predetermined value irrespective of the first and second data signals, if the first control signal is asserted. A first selection circuit selects one of the operation results of the first and second logic gates, and outputs the selected operation result as a first selection signal. A latch circuit latches the first selection signal.
