Abstract
A data interface method includes differentially amplifying differential data signals based on a mode control signal indicating a first mode, transmitting the amplified differential data signals to a receiving semiconductor device via first and second transmission lines, and driving one of the differential data signals and a strobe signal to the first and second transmission lines, respectively, based on the mode control signal indicating a second mode, for transmitting the one of the differential data signals and the strobe signal to the receiving semiconductor device. The receiving semiconductor device samples the received differential data signals according to differential signaling, in response to a controlled sampling clock signal based on the mode control signal indicating a first mode; and samples the one of the differential data signals in response to a strobe signal, received from the transmitting semiconductor device, based on the mode control signal indicating a second mode.
