Abstract
A variety of applications can include systems and methods that control a memory size of a changelog in a storage device, where the changelog is implemented to correlate virtual page addresses to physical addresses in one or more memory devices. The memory size can be controlled by an allocation schema for a scalable memory area for the changelog in the storage device. The allocation schema can include using bitmaps, lists linked to the bitmaps, and a counter to count bits asserted in the bitmaps such that the allocation of memory space in the storage device can depend on usage rather than allocating a large memory space for all possible correlations of virtual page addresses to physical addresses.
