Recent research advocates large die-stacked DRAM caches in many core servers to break the memory latency and bandwidth wall. To realize their full potential, die-stacked DRAM caches necessitate low lookup latencies, high hit rates and the efficient use of off-chip bandwidth. Today's stacked DRAM cache designs fall into two categories based on the granularity at which they manage data: block-based and page-based. The state-of-the-art block-based design, called Alloy Cache, collocates a tag with… CONTINUE READING
