Abstract
A semiconductor apparatus may include a receiver circuit and a termination circuit. The receiver circuit may be coupled to a receiving node, and configured to receive a signal transmitted through a signal transmission line. The termination circuit may be configured to be turned on to set a resistance value of the receiving node in a transition period of the signal, and turned off in a stabilization period of the signal.
Claims17
A semiconductor apparatus comprising:
- a receiver circuit coupled to a receiving node, and configured to receive a signal transmitted through a signal transmission line;
- and
- a termination circuit configured, when the receiver receives the signal transmitted through the signal transmission line, to be turned on to set a resistance value of the receiving node in a transition period in which a level of the signal is changed, and turned off in a stabilization period in which the level of the signal is retained.
A semiconductor apparatus comprising:
- a receiver circuit coupled to a receiving node, and configured to receive a signal transmitted through a signal transmission line;
- a termination clock generator configured to generate a plurality of termination clock signals which are sequentially enabled, based on a clock signal;
- and
- a termination circuit, when the receiver receives the signal transmitted through the signal transmission line, configured to set a resistance value of the receiving node based on an enable signal and the plurality of termination clock signals,
- wherein the plurality of termination clock signals are enabled in a transition period in which a level of the signal is changed and disabled in a stabilization period in which the level of the signal is retained.
