ABSTRACT:
An internal power supply potential generating circuit includes: a control potential generating circuit having four MOS transistors connected in series between a node and a ground potential line, and controlling a pull-up transistor and a pull-down transistor in order that a potential at an output node coincides with a control potential; a monitor potential generating circuit having four MOS transistors connected in series between a prescribed node and a ground potential line, and generating a monitor potential; a potential dividing circuit generating a potential ½ times a reference potential; and a VCC1 generating circuit controlling a potential at the prescribed potential in order that the monitor potential becomes the reference potential. Therefore, an output potential can be controlled with correctness.
