A semiconductor device is configured so that two or more master devices access a slave device via a bus. The semiconductor device includes: a priority generation circuit that generates a priority based on a transfer amount between a specific master device and a specific slave device; and an arbitration circuit that performs an arbitration based on the priority when competition of the accesses occurs.
