1. A cycle control circuit comprising:
- a judgement pulse generation circuit configured to set a predetermined value in response to an initialization signal and configured to generate a judgement pulse in synchronization with a point of time that a time period corresponding to the predetermined value in units of a cycle of a clock signal elapses;
a detection signal generation circuit configured to generate a detection signal from a reference flag in response to the judgement pulse; and
a code generation circuit configured to generate a calibration code for controlling a cycle of a reference signal in response to the detection signal and the judgement pulse.

Abstract
A cycle control circuit may include a judgement pulse generation circuit, a detection signal generation circuit or a flag generation circuit. The judgement pulse generation circuit may be configured to set a predetermined value based on an initialization signal and a period signal, and to generate a judgment pulse. The detection signal generation circuit may be configured to generate a detection signal from a reference flag. The flag generation circuit may be configured to generate a reference flag based on a reference signal. A cycle of the reference signal may be maintained or adjusted based on the reference flag.
