Abstract:
An information processing terminal device, comprising:a first memory for storing files; a second memory for storing a plurality of files, the second memory having a larger memory capacity and a higher power consumption than the first memory; a processing unit configured to read and process files stored in the first memory, and to access the second memory when a desired file does not exist in the first memory; a judgement unit configured to judge whether there is a possibility of external power supply or not; a prohibition unit configured to prohibit activation of the second memory when the judging unit judges that there is no possibility of external power supply; and a control unit configured to select prescribed files that are expected to have probabilities for being accessed during a period in which activation of the second memory is prohibited by the prohibition unit, and to store the prescribed files into the first memory in advance.
