Semiconductor device

A semiconductor device comprising:

• a data pad;
• at least one common node;
• a common path coupled between the data pad and the at least one common node and suitable for outputting a common data signal to the at least one common node based on a data signal and a reference signal;
• at least one merge node;
• a first data path coupled between the at least one common node and the at least one merge node and suitable for outputting, in a first mode, a first data signal to the at least one merge node based on the common data signal and a mode selection signal;
• a second data path coupled between the at least one common node and the at least one merge node and suitable for outputting, in a second mode, a second data signal to the at least one merge node based on the common data signal and the mode selection signal;
• and
• a synchronization path coupled to the at least one merge node and suitable for outputting, in one of the first and second modes, a corresponding signal of the first and second data signals as a data signal synchronized with a data strobe signal.

A semiconductor device comprising:

• a first data path suitable for generating, in a first mode, a first data signal based on a data signal and a reference signal;
• a second data path suitable for generating, in a second mode, a second data signal based on the data signal and the reference signal;
• and
• a synchronization path suitable for outputting, in each of the first and second modes, a selected signal from among the first and second data signals as a data signal synchronized with at least one data strobe signal based on a mode selection signal, the at least one data strobe signal and the first and second data signals.
