ABSTRACT:
An apparatus for receiving a first supply voltage in order to generate an internal voltage includes a control signal generating block for receiving a control enable signal and a clock signal and generating a pumping control signal having a period determined by one of the control enable signal and the clock signal in response to a test mode signal; and a charge pumping block for converting the first supply voltage into the internal voltage in response to the pumping control signal.
