Abstract
A circuit with variable voltage boosting ratios in a memory device for raising a booster line includes the first and second capacitors, and first and second switching means. The first capacitor electrically connects to the booster line for raising the voltage level on the booster line. The second capacitor couples to the booster line through the first switching means and the power line through the second switching means, respectively. When the first switching means is turned on and the second switching means is turned off, the second capacitor boosts the booster line together with the first capacitor. When the first switching means is turned off and the second switching means is turned on, the second switching means is precharged by the power line instead of boosting the booster line.
