Abstract
A semiconductor device includes a strobe transmission circuit configured to output an oscillation strobe signal, through a first delay path circuit, as a strobe signal when a first measurement operation is performed and configured to output the oscillation strobe signal through a second delay path circuit as the strobe signal when a second measurement operation is performed, and a calibration circuit configured to compare the number of times the strobe signal toggles during the first measurement operation to the number of times the strobe signal toggles during the second measurement operation to calibrate the delay amounts of the first and second delay path circuits to be the same.
