SIGNALING METHOD USING CONSTANT REFERENCE VOLTAGE AND DEVICES THEREOF

摘要

A semiconductor device includes a receiver configured to receive a reference voltage via a first input terminal, receive an input signal via a second input terminal, and generate an output signal by comparing the reference voltage to the input signal with each other. A termination circuit associated with the input signal terminal may be adjusted and a logic threshold voltage may be adjusted to accommodate the adjustment in the termination circuit.

1. A semiconductor device comprising:
a receiver configured to receive a reference voltage having a fixed value regardless of a termination operating mode, to receive an input signal from an external device via an input node, and to generate an output signal by comparing the reference voltage with the input signal; and a termination circuit connected to the input node and configured to change the termination operating mode in response to a termination control signal, wherein the termination control signal is associated with a swing level of the input signal.
