Abstract
A word line driving circuit includes a read voltage generator and a word line driver. The read voltage generator precharges a clamp capacitor with a power supply voltage to stably generate a read voltage in response to a read command. A capacitance of the clamp capacitor is varied to compensate for a fluctuation of a power supply voltage level. The word line driver distributes electric charges precharged in the clamp capacitor to a word line in response to a word line selecting signal. Therefore, the word line driving circuit reduces unnecessary power consumption in a standby mode by operating the word line rapidly with charge sharing in a read mode.
