Abstract
A memory-efficient last level cache (LLC) architecture is described. A processor implementing a LLC architecture may include a processor core, a last level cache (LLC) operatively coupled to the processor core, and a cache controller operatively coupled to the LLC. The cache controller is to monitor a bandwidth demand of a channel between the processor core and a dynamic random-access memory (DRAM) device associated with the LLC. The cache controller is further to perform a first defined number of consecutive reads from the DRAM device when the bandwidth demand exceeds a first threshold value and perform a first defined number of consecutive writes of modified lines from the LLC to the DRAM device when the bandwidth demand exceeds the first threshold value.
