Abstract
A data transfer device includes a shifter block that generates first and second input signals and first and second output signals, an input/output control block that selects the first input signal and the first output signal in correspondence to a mode signal and outputs an input control signal and an output control signal for controlling a data input/output operation, or selects the second input signal and the second output signal and outputs the input control signal and the output control signal, and a buffer block that latches first input data or second input data which have different data bit widths according to the input control signal, and outputs first output data or second output data which have different data bit widths according to the output control signal.
