INTERNAL VOLTAGE GENERATOR OF SEMICONDUCTOR MEMORY DEVICE

摘要

An internal voltage generator of a semiconductor memory device is provided to reduce power consumption by enabling a pumping controller and a reference voltage generator. A referent voltage generating part(210) produces a reference voltage, and a pumping controller(220) is enable at an active operation. The pumping controller compares the feedback voltage with the reference voltage and outputs a pumping enable signal based on the result. A storage stores/outputs the pumping enable signal outputted from the pumping controller. The charge pumping part(240) performs charge pumping in response to the pumping enable signal outputted from the storage and drive pumping voltage.
