Abstract
A memory is made up of multiple pages, and different pages can have different priority levels. A set of memory pages having at least similar priority levels are identified and compressed into an additional set of memory pages having at least similar priority levels. The additional set of memory pages are classified as being the same type of page as the set of memory pages that was compressed (e.g., as memory pages that can be repurposed). Thus, a particular set of memory pages can be compressed into a different set of memory pages of the same type and corresponding to at least similar priority levels. However, due to the compression, the quantity of memory pages into which the set of memory pages is compressed is reduced, thus increasing the amount of data that can be stored in the memory.
