Abstract
A skew detection circuit includes a data sensing block configured to sense a first data that is transferred earliest and a last data that is transferred latest among a plurality of data which are transferred through different transfer paths, and generate a sensing result signal; and a detection signal generation block configured to compare an output signal of the data sensing block with a certain time, and generate a skew detection signal.
