ABSTRACT:
An internal potential generation circuit operates with the potential levels of an output node N.sub.H1 of a first boosting circuit and an output node N.sub.H2 of a second boosting circuit maintained in common in response to a high voltage switch circuit attaining a conductive state at the initial stage of the operation of the internal potential generation circuit. After the output potential level of the second boosting circuit arrives at a predetermined potential level, the high voltage switch circuit is cut off, whereby the first and second boosting circuits drive independently the potential level of corresponding output nodes.
