Abstract
A semiconductor apparatus includes a clock path, a command path, a delay monitoring circuit, and an output control circuit. The clock path generates a delay clock signal by delaying a clock signal. The command path generates an output command signal from on one of a command signal and the clock signal, based on a monitoring signal. The delay monitoring circuit generates a delay control signal and a latency control signal based on a phase difference between the delay clock signal and the output command signal, when the monitoring signal is enabled. The output control circuit generates an output enable signal by synchronizing the output command signal with the delay clock signal, based on the latency control signal.
