Abstract
A central processing unit, a read only memory, a random access memory, an oscillator for supplying a clock signal to the central processing unit, a peripheral circuit and a control circuit are provided. The control circuit supplies a first voltage to the central processing unit, the read only memory, the random access memory and the peripheral circuit in synchronization with rising/falling of the clock signal, and supplies a second voltage to the central processing unit with passage of predetermined time after the rising/falling of the clock signal. The first voltage enables the central processing unit, the read only memory, the random access memory and the peripheral circuit to change their operations. The second voltage is lower than the first voltage, and enables the central processing unit, the read only memory, the random access memory and the peripheral circuit to maintain their operations.
