ABSTRACT:
Embodiments are described including those for controlling peak current consumption of a multi-chip memory package during power-up. In one embodiment, each memory device of the multi-chip package includes a power level detector used to compare an internal voltage signal to a threshold. A current limiter controls the ramping rate of the internal voltage signal in response to the power level detector as the internal voltage signal ramps up towards the threshold.
