ABSTRACT:
Disclosed is a DRAM cell which has a transistor and a cell capacitor for storing a charge. Additionally, the cell further includes a second capacitor for charge pumping the cell capacitor, the two capacitors being connected to a common junction. The second end of the charge pump capacitor, namely the end which does not share a common junction with the cell capacitor, is connected to a control line which is driven during writing so as to boost the storage voltage in the cell capacitor. Through this arrangement, the storage voltage of the cell capacitor can be boosted by means other than a word line boost.
