Abstract
According to one embodiment, a skew correcting device includes a skew calculation circuit and a sampling timing correction circuit. The skew calculation circuit calculates a skew between data and a strobe signal based on sampling values obtained by sampling, at a cycle one half of or shorter than one half of a cycle of the strobe signal, the data and the strobe signal respectively based on a same clock. The sampling timing correction circuit corrects the sampling timing of the data based on the skew calculated by the skew calculation circuit.
