A system including a CPU, memory, and compression controller hardware, and implementing a first directory structure included in a first memory wherein CPU generated real memory addresses are translated into one or more physical memory locations using the first directory structure, further includes a second directory cache structure having entries corresponding to directory entries included in the first directory structure. In a first embodiment, the second directory cache structure is implemented as part of compression controller hardware. In a second embodiment, a common directory and cache memory structure is provided for storing a subset of directory entries in the directory structure together with a subset of the memory contents.
