Abstract: A scan chain circuit includes first through N-th flip-flops connected in series to sequentially transfer data in response to a control signal, where N is an integer greater than 1. In the first through N-th flip-flops, the data are transferred in a first direction from the first flip-flop to the N-th flip-flop. The control signal is applied to the first through N-th flip-flops in a second direction opposite to the first direction from the N-th flip-flop to the first flip-flop.
