Abstract: A dual-rail memory circuit having a sleep generation circuit configured to prevent undesired currents from being generated during power-up and while transitioning power states. When a dual-rail memory circuit is powering-up or exiting from a sleep mode, the ramping up of various supply voltage nodes may occur at different rates.
