Delay detecting apparatus of delay element in semiconductor device and method thereof
A delay detecting apparatus detects delay amounts of delay elements in a semiconductor device by using a test mode. The semiconductor device comprises a delay signal detecting unit for detecting delays of delay elements in the semiconductor device by using a signal that is synchronized with an external clock, and a delay signal outputting unit for outputting a delayed signal from the delay signal detecting unit to a data pad by using the signal that is synchronized with the external clock.
