ABSTRACT:
An internal power supply voltage generating circuit of semiconductor memory devices configured such that only a predetermined internal power driver is driven but the remaining internal power drivers are not driven, in a standby mode so that the leakage current in standby mode is reduced and the standby current is thus reduced. Furthermore, the leakage current of an internal power driver that does not operate in the standby mode is reduced using a high voltage as a back bias of the internal power driver.
