Abstract:
1. A semiconductor device, comprising: a signal switch configured to receive differential data signals and a strobe signal, and to output either the differential data signals or one of the differential data signals and the strobe signal, based on a mode control signal; and a signal amplifier configured to differentially amplify the differential data signals output from the signal amplify the one of the differential data signals and the strobe signal output from the signal switch, and to transmit the amplified signals to a receiving semiconductor device via a plurality of transmission lines, wherein the signal amplifier comprises a differential amplifier configured to differentially amplify the differential data signals, which are received from the signal switch based on the mode control signal, and to individually amplify the one of the differential data signals and the strobe signal, which are received from the signal switch based on the mode control signal.
