Abstract
A flip-flop circuit has a master latch circuit and a slave latch circuit. In the flip-flop circuit, the master latch circuit and the slave latch circuit share at least a pair of transistors. In response to the clock signal, the signal held in the master latch circuit can be output at higher speed as the output signal via the intermediate node, the slave latch circuit and the output circuit. The flip-flop circuit can be reduced in cell size and improved in processing speed.
