Abstract
A temperature sensing circuit activates a sensing signal when sensing that a temperature inside a semiconductor integrated circuit is lower than a predetermined temperature. A heat generation control circuit activates a heat generation control signal when the sensing signal is activated. When the heat generation control signal is activated, a current is generated inside a memory circuit to raise the temperature inside the semiconductor integrated circuit.
