Abstract: A controller that reduces power consumption and has improved performance is provided. The controller comprises a processor, and a memory device, wherein the processor is configured to generate a first virtual machine and a second virtual machine, which are different from each other, perform a first operation by using the first virtual machine, perform a second operation different from the first operation by using the second virtual machine, stop the second operation by performing a suspend operation for the second virtual machine, store data for the second virtual machine in the memory device, stop the first operation by performing a suspend operation for the first virtual machine after stopping the second operation, store data for the first virtual machine in the memory device, generate the second virtual machine by using the data for the second virtual machine from the memory device by performing a resume operation for the second virtual machine while the first operation is being stopped, and perform the second operation by using the second virtual machine.
