Abstract: Provided are a semiconductor device and a method for operating a semiconductor device. The semiconductor device includes a clock generating unit receiving a reference clock and generating first and second clocks that are different from each other from the reference clock; a first latch configured to receive input data based on the first clock and to output the input data as first output data; and a second latch configured to receive the first output data based on the second clock and to output the first output data as second output data, wherein a first edge of the first clock does not overlap a first edge of the second clock, and at least a part of a second edge of the first clock overlaps a second edge of the second clock.

Abstract: A multi-bit flip-flop includes: a single scan input pin to receive a scan input signal, a plurality of data input pins to receive first and second data input signals, a first scan flip-flop to select one of the scan input signal and the first data input signal as a first selection signal in response to a scan enable signal and to latch the first selection signal to provide a first output signal, a second scan flip-flop to select one of an internal signal corresponding to the first output signal and the second data input signal as a second selection signal in response to the scan enable signal and to latch the second selection signal to provide a second output signal, and a plurality of output pins to output the first and second output signals, wherein scan paths of the first and second scan flip-flops are connected to each other.
