There is a need to provide a semiconductor device that improves an interrupt capability of a virtual machine. A semiconductor device includes a memory to store a plurality of virtual machines and a virtual machine manager to manage the virtual machines and a CPU to perform the virtual machines and the virtual machine manager. The CPU causes an active virtual machine to perform an interrupt process when information (first information) about an interrupt-processing virtual machine is equal to information (second information) about the active virtual machine. When the first information differs from the second information, the CPU causes the virtual machine manager to stop the active virtual machine and operates the interrupt-processing virtual machine to perform an interrupt process.
