Abstract
A dynamic power control system includes an external power input terminal receiving a first output electric current from a power management circuit outside of the memory device; a variable charge pump receiving a second input voltage and a second input electric current, boosting the second input voltage to a second output voltage, and outputting the second output voltage and a second output electric current to the memory device; and a feedback controller to compare a ratio of the first output electric current to the first input electric current and a ratio of the second output electric current to the second input electric current, and to select one of the power management circuit and the variable charge pump to supply power to the memory device, according to the comparison result.
