Abstract
A reference voltage generating circuit and a standby down-converting circuit or a tuning circuit are located in the periphery of the region where a semiconductor device is formed on a semiconductor chip, and a region including an active down-converting circuit which operates during an active cycle or a drive circuit is located adjacent to a circuit actually consuming a current. According to the semiconductor device, increase in area can be suppressed compared to the structure in which both a standby down-converting circuit or drive circuit and the tuning circuit and an active down-converting circuit are located in the vicinity of each current consuming circuit, thereby achieving efficient arrangement of the internal power supply circuitry. As a result, a semiconductor device having efficiently arranged internal power supply circuitry is provided.
