ABSTRACT:
A complementary metal-oxide semiconductor (CMOS) integrated circuit, such as a dynamic random access memory (DRAM), is powered by supply voltage. The CMOS integrated circuit is divided into n circuit portions including a first circuit portion and a second circuit portion. Control circuitry generates a first powerup control signal. A first switch couples the supply voltage to the first circuit portion based on the first powerup control signal being active. The first powerup control signal is delayed by a selected time delay to produce a second powerup control signal. Alternatively, the second powerup control signal is generated independent of the first powerup control signal, but is active the selected time delay after the first powerup control signal is active. A second switch couples the supply voltage to the second circuit portion based on the second powerup control signal being active.
