Abstract
A system includes a device coupleable to a first memory. The device includes a second memory to cache data from the first memory. The second memory is to store a set of compressed pages of the first memory and a set of page descriptors. Each compressed page includes a set of compressed data blocks. Each page descriptor represents a corresponding page and includes a set of location identifiers that identify the locations of the compressed data blocks of the corresponding page in the second memory. The device further includes compression logic to compress data blocks of a page to be stored to the second memory and decompression logic to decompress compressed data blocks of a page accessed from the second memory.
