Abstract
A pumping voltage generating circuit can include a control information generating block receiving a pumping enable signal and a refresh sequential signal and generating driving force control information, the driving force control information controlled so that a number of pulses of the refresh sequential signal falling within a target pulse number range is generated during the generation of pulses of the pumping enable signal which have the pumping reference number, a pumping generation block generating a pumping voltage with a total pumping force, the total pumping force depending on the data value of the driving force control information, and a level detection block detecting a level of the pumping voltage and generating the pumping enable signal, the pumping enable signal activated when the level of the pumping voltage is outside a target level range, and deactivated when the level of the pumping voltage falls within the target level range.
