Abstract:
1. A semiconductor device, comprising: a first pre-driving unit configured to generate a pull-up driving signal corresponding to a data signal, and transfer the pull-up driving signal to a first transmission line; a second pre-driving unit configured to generate a pull-down driving signal corresponding to the data signal, and transfer the pull-down driving signal to a second transmission line, respectively; a first main driving unit configured to drive an output in response to the pull-up driving signal transferred through the first transmission line; a second main driving unit configured to drive the output in response to the pull-down driving signal transferred through the second transmission line; a termination code generation unit configured to generate a termination code in response to a termination enable signal; a first termination driving unit configured to terminate the first transmission line in response to the termination code; and a second termination driving unit configured to terminate the second transmission line in response to the termination code, wherein the termination code generation unit comprises: a first logic unit configured to perform a NAND operation on the termination enable signal and a power supply voltage to output a first termination code; and a second logic unit configured to perform a NOR operation on an inverted termination enable signal and a ground voltage to output a second termination code.
