Abstract
A memory architecture and method of partitioning a computer memory. The architecture includes a cache section, a setup table, and a compressed storage, all of which are partitioned from a computer memory. The cache section is used for storing uncompressed data and is a fast access memory for data which is frequently referenced. The compressed storage is used for storing compressed data. The setup table is used for specifying locations of compressed data stored within the compressed storage. A high speed uncompressed cache directory is coupled to the memory for determining if data is stored in the cache section or compressed storage and for locating data in the cache.
