ABSTRACT:
A semiconductor device contains circuits composed on a semiconductor substrate which are divided at least into two circuit blocks as seen from the aspect of supplying electrical power, and the pad and wiring for feeding a supply potential and/or grounding potential to the first circuit block, and the pad and wiring for feeding the supply potential and/or grounding potential to the second circuit block other than the first circuit block are electrically independent of each other. In this constitution, it is possible to prevent malfunctions of the second circuit block and distortions of the output signal due to fluctuations of the supply potential or grounding potential occurring during operation of the first circuit block. It is also possible to prevent malfunctions of the first circuit block and distortions of the signal on the first circuit block due to fluctuations of the supply potential or grounding potential occurring due to a malfunction of the second circuit block.
