PURPOSE: A reference voltage generator is provided, which can decrease a current and a layout area by generating two independent reference voltages with one reference voltage generator. CONSTITUTION: A reference voltage generation part(210) makes a constant voltage(VR0) using an external voltage, and a level trimming part(220) generates various output voltages(VR1,VR2) by receiving the output value(VR0) of the reference voltage generation part. An internal voltage driving part(230) generates an internal voltage(Vint) by receiving the output value(VR1) of the level trimming part, and a reference voltage generation driver(240) generates a reference voltage(Vref) by receiving the output value(VR2) of the level trimming part.
