The copy unit copies the interrupt monitoring program from the dynamic memory to the static memory in response to the detection signal, and runs the interrupt monitoring program in the static memory for monitoring whether an interrupt signal is generated. The set unit sets the dynamic memory into a self-refresh mode in response to the detection signal.
