Abstract: Provided are an apparatus and a method for adjusting a skew between data and a clock. The apparatus driven by a supply voltage includes a clock circuit that adjusts a skew between data and a clock. The clock circuit performs a first loop operation through a first loop and a second loop operation through a second loop, based on a phase difference between data and a clock. The first loop operation is performed until there is no phase difference between the data and the clock, and the second loop operation is performed until a first slope representing a change in delay of the data with respect to the levels of the power voltage and a second slope representing a change in delay of the clock become identical to each other.
