US Patent 11756605 Semiconductor device

A semiconductor device capable of decreasing a jitter component is provided. A first calibration circuit searches a second delay value of a data delay circuit while determining a delay value of a strobe delay circuit to be a first delay value that is larger than the minimum value and smaller than the maximum value. A second calibration circuit determines a first corrected delay value and a second corrected delay value by shifting both the first delay value and the second delay value by the same correction value in a direction toward the minimum value, and sets the first corrected delay value and the second corrected delay value to the strobe delay circuit and the data delay circuit, respectively.
