ABSTRACT:
A dynamic random access memory in which data are successively read out responsive to a read command signal is provided with a boosting circuit device. The boosting circuit device has a pumping circuit operable with a first electric power source at a first voltage and responsive to a control clock signal for producing a second electric power at a second voltage boosted higher than the first voltage of the first electric power. A one-shot pulse generator is provided for generating a single pulse from which a pre-pumping pulse is produced to be included in the control clock signal. Thus, the control clock signal contains a pre-pumping pulse and a plurality of clock pulses following the pre-pumping pulse, so that the second voltage of the second electric power has been boosted higher than the first voltage of the first electric power by the pre-pumping pulse in advance of a successive readout of data.
