摘要： A word line driving circuit, which may include a read voltage generator and a word line driver. The read voltage generator may precharge 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 may be varied to compensate for a fluctuation of a power supply voltage level. The word line driver may distribute 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 may reduce unnecessary power consumption in a standby mode by operating the word line rapidly with charge sharing in a read mode.

The example voltage generator may include a voltage comparison block which generates an output voltage in response to a read command, the output voltage corresponding to a difference between a reference voltage and a determination voltage and a voltage generation block which outputs the determination voltage and a comparison voltage in response to the read command, an inverse read command having a phase opposite that of the read command, a switching pulse signal and the output voltage. A first example method may include outputting a determination voltage and a comparison voltage in response to a read command, an inverse read command having a phase opposite that of the read command, a switching pulse signal and an output voltage, the output voltage generated in response to the read command and corresponding to a difference between the reference voltage and the determination voltage. A second example method may include maintaining a comparison voltage at a first voltage level if a read command is disabled and transitioning the comparison voltage to a second voltage level if the read command is enabled by discharging electric current along a first path, the first path connected to a first node coupled to at least one resistor, and a second path, the second path connected to a second node coupled with a switched capacitor circuit, the switched capacitor circuit including a capacitor which is selectively connected to the second node in response to the enabled read command.
