PHYSICAL MEMORY COMPRESSION

A memory management system includes a physical memory associated with a computing device and a memory manager. The memory manager is configured to manage a shared memory cache as part of a compression of the physical memory using a cache compression algorithm, wherein a compression block size for the compression is a single cache line size. The physical memory includes a sector translation table (STT) region and a sector memory region. The memory manager uses a memory descriptor defined by an STT entry having a cache line map and a plurality of sector pointers to load cache from the physical memory to a level 3 Cache. The cache line map contains cache line metadata including a size of each cache line, a location of the cache line in one of the sectors pointed to by the STT entry, and a plurality of flags.
