In a multi-valued voltage generating circuit including a voltage divider connected between first and second nodes and formed by a series of resistors, and an output circuit, connected to the first and second nodes and nodes of the resistors, for selecting one of voltages at the first and second nodes and the nodes of said resistors and generating the one of voltages at an output terminal, first and second control voltage circuits are connected to the first and second nodes to control an output voltage at the output terminal to compensate for fluctuations of the threshold voltages of MOS transistors of the output circuit. Also, first and second current control circuits are connected to the first and second nodes, to control currents flowing through the series of resistors to control a difference in potential between the first and second nodes at a certain value and to compensate for the fluctuation of the resistance.
