1. A method, comprising: operating a plurality of first memory regions of a memory device at a first operating power level; operating a plurality of second memory regions of the memory device at a second operating power level different from the first operating power level; based on a classification of the first memory object being movable, selecting at least one of the plurality of first memory regions; determining available memory space in the at least one of the plurality of first memory regions; based on the available memory space in the at least one of the plurality of first memory regions being sufficient to allocate the first memory object: allocating at least a portion of the available first memory space to the first memory object; and placing the first memory object in the at least one of the plurality of first memory regions; and based on the available memory space in the at least one of the plurality of first memory regions not being sufficient to allocate the first memory object: selecting a second memory object in the at least one of the plurality of first memory regions for relocation based at least in part on use of the second memory object; identifying a queue including the selected second memory object; relocating the second memory object to at least one second memory region based at least in part on the queue; and placing the first memory object in the at least one of the plurality of first memory regions.
