发明名称 Semiconductor device and semiconductor system including the same
摘要 A semiconductor device includes a clock division block suitable for dividing a frequency of a source clock and generating first and second internal clocks; a strobe division block suitable for dividing a frequency of a strobe signal, and generating first and second internal strobe signals; and a phase difference detection block suitable for generating and alternately outputting first and second detection information as a detection result information.

主权项 1. A semiconductor device comprising: a clock division block suitable for dividing a frequency of a source clock at a preset rate, and generating first and second internal clocks, which have a first phase difference from each other; a strobe division block suitable for dividing a frequency of a strobe signal at the preset rate, and generating first and second internal strobe signals, which have a second phase difference from each other; and a phase difference detection block suitable for generating and alternately outputting first and second detection information as detection result information, wherein the first detection information represents a combination of logic values of the first and second internal clocks detected at an edge of the first internal strobe signal, and wherein the second detection information represent a combination of logic values of the first and second internal clocks detected at an edge of the second internal strobe signal.
