Abstract
A semiconductor system includes a first semiconductor device suitable for outputting an external command and a termination control signal and being inputted with a data signal; and a second semiconductor device suitable for generating a termination enable signal in response to the external command and the termination control signal, generating a pull-up signal in response to the termination enable signal, and generating a pull-down signal in response to the termination enable signal and a test mode signal.
Claims6
A semiconductor device comprising:
- a pull-up signal generation unit suitable for generating a pull-up signal in response to a termination enable signal and a pre-pull-up signal;
- a pull-down signal generation unit suitable for generating a pull-down signal in response to a test mode signal, the termination enable signal, and a pre-pull-down signal, and
- wherein the termination enable signal is a signal which is generated in response to an external command and a termination control signal and the pull-up signgal controls a termination operation that couples a first resistor elelment between a first power supply voltage and a first node.
