Abstract: The time required for transition from an on-state to a suspend state is reduced. An electronic apparatus includes: a memory and a memory; a current control unit that performs a control to shut off supply of current to the memory; and a memory management unit that allocates a memory region in either the memory or the memory based on preference information indicating a memory region that needs to be preferentially allocated in the memory. For example, the preference information includes association with a first priority as a degree at which a memory region to be used by an application needs to be preferentially allocated in the memory, and when receiving a request of allocation of the memory region from the application, the memory management unit more preferentially allocates the memory region in the memory as the first priority associated with the application in the preference information is higher.
