The present invention provides a system LSI that integrates, on a single semiconductor, a logic circuit, a CPU, and a program memory storing a program of the CPU. The system LSI includes a program eraser erasing contents stored in the program memory, and at least two program erasing trigger terminals controlling execution of the program eraser. The program eraser erases a program stored in the program memory on the basis of potentials of the two program erasing trigger terminals. |
