Patent ID: 7495992

Claim:
A system for increasing a wordline voltage level V WL of a selected wordline having a wordline capacitance C WL from an initial wordline voltage level V WLI to a pre-determined target voltage level V WLT , comprising: a wordline voltage supply arranged to provide a wordline voltage; a first switch arranged to connect the wordline voltage supply to the selected wordline at a first node through a load capacitance C L in response to a first signal; and a second switch arranged to disconnect the wordline supply voltage from the selected wordline at a second node such that the wordline capacitance C WL and a load capacitance C L are connected in a series configuration with respect to the first node, wherein a wordline voltage supplied by the wordline voltage supply at the first node results in a charging current at the first node that charges up the series combination of the wordline capacitance C WL and the load capacitance thereby increasing the wordline voltage level V WL .
