Abstract: The present disclosure discloses a memory management method, an electronic apparatus and a device with a storage function. The method includes: acquiring a currently required reserved memory value of a component/application, where the reserved memory is a part of physical memory reserved by an operating system for the component/application and not to be mapped into running memory; judging whether the currently required reserved memory value is smaller than an allocated reserved memory value, where the allocated reserved memory value is a reserved memory size allocated by the operating system to the component/application; and when the currently required reserved memory value is smaller than the allocated reserved memory value, recovering redundant reserved memory and reallocating the recovered reserved memory for use as running memory. In the above manner, the present disclosure can increase a utilization ratio of memory.
