Abstract
A sensing technique uses a variable precharge voltage sensing with a single bitline swing in a DRAM cell or array of DRAM cells so that the power dissipation is reduced. The bitline precharge voltage varies from one RAS cycle to the next RAS cycle depending upon the level of the data in the accessed cells. Such an arrangement eliminates the need for a reference voltage generator since the precharge voltage is not the same voltage for each RAS cycle.
