Abstract:
Provided is a clock delay detecting circuit and semiconductor apparatus using the same that is capable of generating a period signal whose period is a delay time of a clock, dividing the period signal, and counting the divided period signal. The clock delay detection circuit comprises a period signal generating unit configured to generate a counting control signal, a period signal dividing unit configured to generate a counting enable signal by dividing the counting control signal, and a counting unit configured to generate a delay information signal by counting the counting enable signal with a clock, wherein the counting control signal has a period with a predetermined time.
