Abstract:
A voltage generating circuit includes a first charge pumping part and a second charge pumping part. The first charge pumping part pumps a switching voltage, in response to a reference voltage, to output a first voltage. The second charge pumping part pumps the switching voltage, in response to the first voltage, to output a second voltage that is lower than the first voltage that is varied in accordance with time.
