Abstract
An information processing apparatus includes a first memory configured to store first conversion information used for converting a virtual address to a physical address of a memory region to access data stored in the memory region; a second memory configured to store second conversion information used for converting a virtual address to a logical block address of a storage device to access data stored in the storage device; memory management circuitry configured to execute a first processor a second process, according to an access destination of a first virtual address, the first process includes address conversion on the first virtual address using the first conversion information or the second conversion information and memory access to the memory region based on a result of the address conversion, the second process including notification of a first logical block address associated with the first virtual address to an operating system.
