Claim 3:
4. The semiconductor device of claim 3, wherein the comparison driving circuit comprises:
a current sourcing circuit configured to:
regulate, during an activation period of the clock signal, an amount of current provided to a first current path according to the second signal inputted through the third transmission path, and
regulate, during the activation period, an amount of current provided to a second current path according to a reference voltage having a voltage level corresponding to half of the second voltage level; and
a sensing driving circuit configured to:
pull-up or pull-down drive, during the activation period, the first or second transmission path to the first power supply voltage or the ground voltage, respectively, by sensing and amplifying a difference between amounts of current flowing through the first and second current paths, and
drive, during the activation period, the first or second transmission path to a voltage level corresponding to the preset logic level in response to the enable signal.
