ABSTRACT:
A semiconductor device includes a first signal generator that generates a plurality of second signals having a delay relative to a first signal and having states that change at different timings. A second signal generator generates a third signal having a delay relative to the first signal. A detector detects a delay amount based on the states of the second signals when a state of the third signal changes. The first signal generator and the second signal generator are different from each other in an amount of change in delay relative to a change in an operating state.
