Abstract
An internal power supply potential generation circuit includes an overcharge prevention circuit connected to an internal power supply node. The overcharge prevention circuit includes a circuit outputting a signal to be determined that is determined by an internal power supply potential, a differential amplification circuit amplifying a difference in potential between the signal to be determined and a reference potential for output to a node as a signal indicating that current should be drawn, and a current draw circuit drawing current from the internal power supply node in response to the signal indicating that current should be drawn. Thus the semiconductor integrated circuit device of interest can provide a steady internal power supply potential.
