<p>PROBLEM TO BE SOLVED: To solve the problem that useless currents flow to an external input terminal regardless of the operating state of an internal circuit when an input voltage to be applied to the external input terminal is not decided sole in a semiconductor device capable of turning its own internal circuit into a waiting state for reducing power consumption. SOLUTION: In a semiconductor device 10, at the time of turning an internal circuit 12 into a waiting state, an input signal to the internal circuit 12 is held by a latch circuit 11b, and the feeding line of the input signal is disconnected, and at the time of restoring the internal circuit 12 into an operating state, the feeding line of the input signal is reconnected, and then the latch of the input signal is released.</p> |
