Electronic apparatus and control method for adjusting priority of an application based on activations

An electronic apparatus comprising:

• a plurality of volatile memories that include a first memory and a second memory;
• a current control circuit that performs a control to shut off supply of current to the second memory;
• and
• a memory management circuit that allocates a memory region in either the first memory or the second memory based on a first threshold and preference information indicating a memory region that needs to be preferentially allocated in the first memory,
• wherein
• the preference information includes association between an application and a first priority, the application operating using the plurality of the volatile memories, the first priority being a degree at which a memory region to be used by the application needs to be preferentially allocated in the first memory,
• the memory management circuit acquires a frequency at which the application is activated,
• the memory management circuit calculates an adjusted first priority using the first priority associated with the application in the preference information and the frequency at which the application is activated, and calculates an adjusted first threshold using the first threshold and the frequency at which the application is activated, and
• when the memory management circuit receives a request of allocation of the memory region from the application, the memory management circuit allocates the memory region in the first memory if the adjusted first priority associated with the application in the preference information is higher than the adjusted first threshold.
