Abstract: A semiconductor device for controlling a power-up sequence is provided. The semiconductor device includes a plurality of chips. Each of the chips includes a power-up sequence controller configured to differently control generation sequences of internal source voltages. The power-up sequence controller changes the generation sequences of the internal source voltages in response to a power stabilization signal which is generated according to an external source voltage applied thereto in powering up the semiconductor device. Accordingly, a power-up current which is generated according to the internal source voltages being generated has a peak current distribution where a peak current may be equally distributed.

Abstract: An input data alignment circuit includes a data sampler, a frequency divider, a polarity determination block, and a data alignment block. The data sampler provides a data sequence based on data serially input according to a data strobe signal. The frequency divider generates a data alignment signal based on a divided frequency of the data strobe signal. The polarity determination block determines a polarity of the data alignment signal and provides a control signal based on the determined polarity. The data alignment block aligns the data sequence in parallel according to data alignment signal and control signal and generates output data.
