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.
