'''Virtual Memory Compression''' is a [[memory management]] technique that utilizes [[data compression]] to reduce the size or number of [[paging]] requests to/from [[auxiliary memory]]. Virtual memory compression is distinct from [[garbage collection]] systems which remove unused memory blocks and in some cases consolidate used memory regions and reduce fragmentation for efficiency. Virtual memory compression is also distinct from [[context switching]] systems, such as Connectix’s RAM Doubler and Apple OS 7.1, in which inactive processes are suspended and then compressed.<ref name="PAT-5559978"/><ref name="PAT-5785474"/>
