Abstract
A semiconductor device includes a redundancy control signal generation circuit configured to generate a redundancy control signal by determining whether a row address for an active operation has been repaired through a soft post package repair operation and determining whether a row hammer phenomenon has occurred with respect to the row address. The semiconductor device also includes a first selection address generation circuit configured to generate a first selection address for driving a sub word line or a redundancy word line from one of a repair address and a first internal address, based on the redundancy control signal. The semiconductor device further includes a second selection address generation circuit configured to generate a second selection address for driving the sub word line or the redundancy word line from one of a fixed address and a second internal address, based on the redundancy control signal.
