ABSTRACT:
An internal voltage generating circuit of a semiconductor device for receiving an external voltage and generating an internal voltage. In a first voltage interval of the external voltage the internal voltage increases linearly according to the external voltage until a reference voltage is reached. In a second voltage range of the external voltage the internal voltage remains at the reference voltage. After the second voltage range, the internal voltage sharply increases and increases linearly thereafter. Accordingly, the circuit can improve the reliability of the tested semiconductor device.
