Abstract

A design structure for a cache memory system (200) having a cache memory (204) partitioned into a number of banks, or “ways” (204A, 204B). The memory system includes a power controller (244) that selectively powers up and down the ways depending upon which way contains the data being sought by each incoming address (232) coming into the memory system.
