A virtual machine system comprises: a processor for executing a secure operating system and a normal operating system; and a cache memory. The cache memory stores data in a manner that allows for identification of whether the data has been read from a secure storage area of an external main memory. The cache memory writes back data to the main memory in a manner that reduces the number of times data is intermittently written back to the secure storage area which occurs when the processor is executing the normal operating system.
