ABSTRACT:
A temperature sensing circuit has numerous trip points in conformity with a temperature change without adding decrease resistance branches, so as to obtain a fine control based on the temperature change. Accordingly, when employed in a semiconductor memory device, the temperature sensing circuit substantially reduces the consumption of refresh electrical power in a stand-by state without decreasing the reliability of the semiconductor memory device.
