ABSTRACT:
A data input device of a semiconductor memory device can reduce unnecessary current consumption occurring according to a setting of a bandwidth. The data input device includes: a bandwidth signal input part for receiving a bandwidth signal for setting a data bandwidth to output an internal bandwidth signal; a synchronization control part for generating synchronization signals and restrict-synchronization signals in synchronization with a data strobe signal, an activation of the restrict-synchronization signals being restricted through the internal bandwidth signal; a first data input part for aligning the data in response to the synchronization signals; and a second data input part for aligning the data in response to the restrict-synchronization signal and the internal bandwidth signal.
