ABSTRACT:
A temperature sensing circuit and method are provided. An example temperature sensing circuit includes a temperature sensing unit that outputs a temperature signal indicating whether the temperature in the semiconductor device is higher or lower than a reference temperature in response to a first current control signal or a second current control signal by using a first current level that is increased when the temperature rises and a second current level that is reduced when the temperature rises. The temperature sensing unit also includes a storage unit that stores and outputs the temperature signal, and a controller that changes the first current level or the second current level in response to the temperature signal output from the storage unit and generates the first current control signal or the second current control signal used to control the reference temperature.
