An internal voltage generating circuit may include a first pull up resistor activated by a first range signal and connected between a pull up voltage terminal and a pull up common node; a second pull up resistor activated by a second range signal and connected between the pull up voltage terminal and the pull up common node; a first pull down resistor activated by the first range signal and connected between a pull down voltage terminal and a pull down common node; a second pull down resistor activated by the second range signal and connected between the pull down voltage terminal and the pull down common node; a resistor string including a plurality of series resistors connected between the pull up common node and the pull down common node; and a voltage selection circuit select voltage in response to voltage selection information. |
