A deskew circuit includes, for clock and every bit of data, a variable delay circuit between a receiver that receives data and a flip-flop that first latches the data, in which a detecting pattern to detect a stable region for receiving data is repeatedly sent before implementing a data transfer, a delay value with which the starting edge an ending edge of the data match the rising edge of the clock is found for the variable delay circuit, and a delay value with which the transfer data can be received in a stable manner is set based on the delay value of the variable delay circuit.
