ABSTRACT:
An internal voltage converter in semiconductor integrated circuit, comprises an oscillator, a sub circuit including a buffer and a charge-pumping circuit and a power part, a main circuit including a buffer and a charge-pumping circuit and a power part, and a detector. A plurality of voltage converting stages are composed in parallel to be divided when operating so that the unnecesary consumption of the power is reduced in the case of providing the stand-by power and the stability of the internal power supply voltage is also improved.
