ABSTRACT
This work efficiently enables conventional block sizes for very large die-stacked DRAM caches with two innovations: it makes hits faster with compound-access scheduling and misses faster with a MissMap. The combination of these mechanisms enables the new organization to deliver performance comparable to that of an idealistic DRAM cache that employs an impractically large SRAM-based on-chip tag array.
