TicToc: Enabling Bandwidth-Efficient DRAM Caching for both Hits and Misses in Hybrid Memory Systems
Vinson Young, Zeshan Chishti, Moinuddin K. Qureshi
This paper investigates bandwidth-efficient DRAM caching for hybrid DRAM + 3D-XPoint memories. 3D-XPoint is becoming a viable alternative to DRAM as it enables high-capacity and no…

Improving DRAM Performance by Parallelizing Refreshes with Accesses
Kevin K. Chang, Donghyuk Lee, Zeshan Chishti +4
Modern DRAM cells are periodically refreshed to prevent data loss due to leakage. Commodity DDR DRAM refreshes cells at the rank level. This degrades performance significantly beca…
