<p>A portable information processing terminal device, realizing both a low power consumption and a large memory capacity, is formed by a first memory (17) for storing files, a second memory (16) 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 (11) 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 (103) configured to judge whether there is a possibility of external power supply or not, a prohibition unit (104) 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 (102) 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. <IMAGE></p> |
