Abstract
Memory objects may be allocated and re-allocated within a computer system to consolidate infrequently used memory objects to memory regions that may be operated at lower power. During initial allocation of memory objects, the objects may be placed into high power regions. During subsequent periodic analysis, memory objects in high power regions that are infrequently used may be relocated to lower power regions while memory objects in low power regions that are frequently used may be moved to the high power regions. Various heuristics or logic may be used to handle unmovable objects, shared objects, and other types of objects.
Claims8
A memory having instructions stored thereon that, in response to execution by a processing device, cause the processing device to perform operations comprising:
- determining whether to associate a first memory object of a memory array with a second memory object of the memory array;
- retaining first information about a memory region that includes the first memory object and the second memory object in response to determining to associate the first memory object with the second memory object;
- wherein the first information includes at least an assigned power level classification of the memory region;
- and
- controlling power settings of a portion of the memory array at a granularity finer than rank level based on the retained first information.
