Abstract
A semiconductor device includes a phase control signal generation circuit, a phase detection circuit, and a selection/transmission circuit. The phase control signal generation circuit outputs one of a command-shifted signal generated from a command/address signal and a clock-shifted signal generated from a clock signal as a phase control signal, based on a leveling enablement signal. The phase detection circuit detects a phase of a leveling clock signal in synchronization with the phase control signal to generate a detection signal. The selection/transmission circuit outputs the detection signal as one of a phase detection signal and a phase adjustment signal based on the leveling enablement signal.
