ABSTRACT:
The present invention provides a semiconductor apparatus including an internal clock generating unit and a data storing unit. The internal clock generating unit generates an internal clock signal based on an external clock signal and a clock control signal. The data storing unit which operates data processing based on the internal clock signal. The internal clock generating unit carries out synchronous control such that the internal clock signal is synchronized with the external clock signal. The data storing unit generates the clock control signal based on the data processing and outputs the clock control signal to the internal clock generating unit to control the synchronous control. The data storing unit may controls the internal clock generating unit such that the synchronous control is adjourned or restrained temporarily while the data processing is a data reading process.
