Abstract
A word line voltage boosting circuit varies a word line output voltage according to variation of the number of the word lines to be activated. A boosting circuit boosts a word line voltage which has been precharged to a first level voltage to a second level voltage in response to an activation signal. A voltage adding circuit further boosts the word line voltage to a third voltage level by adding a predetermined voltage to the second level voltage if the number of the word lines to be activated increases. A driving circuit includes a bootstrap circuit for stably providing the boosted word line voltage to an output line.
