Abstract
A semiconductor device temperature sensor produces a reference level for temperature detection from two or more reference levels of different temperatures to detect a temperature. The temperature sensor is applied for detecting the temperature of a semiconductor storage device having a memory unit which requires a refresh action. A refresh cycle control circuit provided in the semiconductor storage device controls the cycle of the refresh action for the memory unit in response to an output of the temperature sensor.
