Abstract:
A semiconductor device, comprising:a first terminal to receive first data and second data which is input after said first data, said first and second data being supplied externally;a second terminal to receive, in synchronization with said first and second data, a strobe signal which is supplied externally;a third terminal to receive a complementary strobe signal which is complementary to said strobe signal and is supplied externally;a data input circuit to receive said first and second data in response to said strobe signal and said complementary strobe signal in order to output first and second internal data corresponding to said first and second data, respectively,said data input circuit including a selection circuit to select, as a first data reception edge at which said first data is received, one of a first edge of said strobe signal corresponding to said first data and a first complementary edge of said complementary strobe signal corresponding to said first data and then select, as a second data reception edge at which said second data is received, one of a second edge of said strobe signal corresponding to said second data and a second complementary edge of said complementary strobe signal corresponding to said second data that is input later; andan internal circuit operating according to said first and second internal data.
