A negative voltage supply device includes a negative voltage detector and a negative voltage pumping unit. The negative voltage pumping unit pumps a negative voltage in response to a detection signal. The negative voltage detector detects a level of a negative voltage by using a first element and a second element, which are different in the degree of change in their respective resistance values depending on the temperature, and outputs the detection signal. The detection signal informs the negative voltage pumping unit that pumping of the negative voltage is no longer needed.
摘要:
A voltage generator for use in a semiconductor memory device includes an output voltage controller for generating a bias voltage using a reference voltage of which a voltage level is half of a core voltage level. Pull-up/pull-down driving signals are output by generating a voltage which is higher or lower than the reference voltage by a threshold voltage. An output driver generates a bit line precharge voltage in response to the pull-up driving signal or the pull-down driving signal. Drive controllers interrupt off-leakage current of the output driver. One drive controller is disposed between the output driver and a core voltage terminal and another drive controller is between the output driver and a ground voltage terminal.
