Abstract
A system for charging a low voltage power domain in a low power DRAM includes: a first capacitor, for providing a local domain power voltage supply; a first transistor, coupled to the first capacitor and a voltage supply and turned on by a powerdown signal, the first transistor for decoupling the first capacitor during powerdown mode, and charging the capacitor to provide the local domain power voltage supply when exiting powerdown mode; a second capacitor selectively coupled to the voltage supply or the local domain voltage power supply; and a second transistor, coupled to the second capacitor, the powerdown signal, and the local domain power voltage supply, for decoupling the second capacitor from the local domain power voltage supply during powerdown mode and coupling the second capacitor to the local domain power voltage supply when exiting powerdown mode.
