<p>A period signal generating circuit includes a control voltage generating unit which selects one of first and second temperature voltages varying a level by a temperature and a third temperature voltage having a constant level by a temperature, and outputs the selected voltage as a control voltage; and a period control unit which determines a current amount discharged from an internal node in response to the control voltage, and outputs a period signal whose period is determined by the level of an internal signal outputted from the internal node.</p> |
