A reference voltage generating circuit comprises: a monitor circuit, including a low threshold voltage PMOS transistor, a low threshold voltage NMOS transistor, and a resistor having a predetermined resistance which are connected in series, for generating a reference voltage at one end; and an additional circuit for supplying a monitor current to the monitor circuit and for controlling the other end of the monitor circuit to be at a constant voltage, wherein a voltage value of the reference voltage is corrected within a range corresponding to a process fluctuation from a predetermined center value, based on the monitor current changing in response to the process fluctuation.
