Abstract
Provided are semiconductor devices. A semiconductor device includes a processor which provides a virtualization function for a physical device to a first guest operating system and a second guest operating system; and an SFR (Special Function Register) which is electrically connected to the processor, and includes a first region allocated to the first guest operating system and a second region allocated to the second guest operating system, wherein information on a first data access request provided from the first guest operating system is stored in the first region, and information on a second data access request provided from the second guest operating system is stored in the second region, and the processor generates a first interrupt and a second interrupt designated to the first guest operating system and the second guest operating system, respectively, in response to the first data access request and the second data access request.
