Architecting On-Chip DRAM Cache for Simultaneous Miss Rate and Latency Reduction.

On-chip dynamic random access memory (DRAM) cache has been recently employed in the memory hierarchy to mitigate the widening latency gap between high-speed cores and off-chip memory. Two important parameters are the DRAM cache miss rate (D$-MR) and the DRAM cache hit latency (D$-HL), as they strongly influence the performance. These parameters depend upon the DRAM set mapping policy. Recently pro...
