Abstract
An on die thermal sensor (ODTS) of a semiconductor memory device includes a high voltage generating unit for generating a high voltage having a voltage level higher than that of a power supply voltage of the semiconductor memory device; and a thermal information output unit for sensing and outputting a temperature as a thermal information code, wherein the thermal information output unit uses the high voltage as its driving voltage.
