SEMICONDUCTOR DEVICE AND FAULT DETECTION METHOD THEREFOR

摘要

According to one embodiment, a semiconductor device includes a memory-transfer control unit that controls data transfer between a memory and a sound unit. A plurality of sound data transfer routes are configured by one memory-transfer control unit and one sound unit. The semiconductor device outputs reproduction sound data via at least one sound data transfer route and acquires at least two pieces of recording sound data on account of one piece of reproduction sound data via at least two sound data transfer routes.
