摘要： A semiconductor apparatus includes a delay circuit to apply delay to an input signal, a phase detector to detect a phase of an output signal which is outputted from the delay circuit, a filter to set a range of the phase of the output signal for stable operation based on phase information outputted from the phase detector, a counter to count a number of detections of the output signal when the phase deviates from the range for stable operation, a discount controller to generate a discount signal indicating a discount number for the number counted by the counter, in accordance with an operating condition or an external factor outside the delay circuit and an error detector to determine whether or not an error of the phase of the output signal has occurred based on the number counted by the counter and a discount number indicated by the discount signal.

摘要： In a semiconductor device, a selector selects a different reference voltage depending on whether the impedance of a transmitter or of a receiver is to be adjusted, and causes a reference voltage generator to generate the selected reference voltage. The reference voltage generator generates the reference voltage selected by the selector and applies the generated reference voltage to an impedance adjuster. The impedance adjuster adjusts the impedance of the transmitter and the impedance of the receiver, separately from each other, in accordance with the input reference voltage.
