Abstract:
Compressed memory systems are provided to reduce latency associated with accessing compressed memory using stratified compressed memory architectures and memory organization protocols in which a region of compressed main memory is allocated as a direct access memory (DAM) region for storing uncompressed data items. The uncompressed data items in the DAM region can be directly accessed, speculatively, to serve access requests to main memory, requiring access to compressed memory in the event of a DAM miss.
