Abstract
A memory device includes an array of memory cells and a plurality of peripheral circuits operably coupled to the memory array. A power control circuit may be configured to individually control an application of power to each of the plurality of peripheral circuits and the array of memory cells. Inserting a switch device across the different power domains to achieve the same sequential wake-up path for the peripheral circuits connected to different power domains reduces peak current.
