SEMICONDUCTOR DEVICES AND ELECTRONIC SYSTEMS INCLUDING THE SAME

摘要

Semiconductor devices are provided. The semiconductor device includes an internal clock generator and an internal strobe signal generator. The internal clock generator generates an internal clock signal having a frequency which is higher than that of an input clock signal according to a phase difference between the input clock signal generated from an external device and a first input control signal. The internal strobe signal generator generates an internal strobe signal having a frequency which is higher than that of an input strobe signal according to a phase difference between the input strobe signal generated from the external device and a second input control signal.

1. An electronic system comprising:
a first semiconductor device configured to output a clock signal, a strobe signal, a first control signal having a predetermined phase difference from the clock signal and a second control signal having the predetermined phase difference from the strobe signal; and a second semiconductor device configured to generate an internal clock signal having a higher frequency than the clock signal according to a phase difference between the clock signal and the first control signal and to generate an internal strobe signal having a higher frequency than the strobe signal according to a phase difference between the strobe signal and the second control signal to receive and/or output data.
