Semiconductor device including clock signal generation unit

Abstract

A semiconductor device for stably generating a clock signal from a strobe signal includes a processor, a clock signal generation unit receiving a first strobe signal and a second strobe signal to generate the clock signal, and a data reception unit receiving at least one data signal to provide the received data signal to the processor. The clock signal generation unit may comprise a strobe comparator comparing a voltage of a first input terminal with that of a second input terminal to output logic high or logic low, a first switch selectively connecting one of a first and a second signal line to the first input terminal, a second switch selectively connecting one of the second signal line and a reference line to the second input terminal, and a voltage stabilizing circuit pulling up/down at least one of a voltage of the first and the second signal line.
