Abstract
A semiconductor device includes first and second circuits disposed separately from each other. The first circuit may include: a counting unit suitable for generating count codes, each bit of which is cyclically changing, wherein the count codes include a number of toggles of a sampling signal toggling with a preset frequency representing a distance of single round trip of the sampling signal between the first and second circuits; and a pulse generation unit suitable for generating a measurement pulse according to the count codes representing the distance, wherein the pulse generation unit determines a pulse width of the measurement pulse according to the distance.
