Abstract:
An information processing apparatus includes first and second power feed control portions and a storage processing portion. The first power feed control portion stops power feed to a nonvolatile first storage portion when reading or writing data from/to the first storage portion is completed. In a case where power feed to the first storage portion is stopped, the storage processing portion stores specific data among data stored in the first storage portion into a second storage portion. When an access request for accessing data in the first storage portion has been received: when access-target data specified in the access request is not stored in the second storage portion, the second power feed control portion resumes power feed to the first storage portion; and when the access-target data is stored in the second storage portion, does not resume the power feed to the first storage portion.
