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.
