Exploiting NVM in Large-scale Graph Analytics

Willy Zwaenepoel, Jasmina Malicevic

Data center applications like graph analytics require servers with ever larger memory capacities. DRAM scaling, how- ever, is not able to match the increasing demands for ca- pacity. Emerging byte-addressable, non-volatile memory technologies (NVM) offer a ...

Approximate Computing With Unreliable Dynamic Memories

Andreas Peter Burg, Adam Shmuel Teman, Robert Giterman, Georgios Karakonstantis, Shrikanth Ganapathy

Embedded memories account for a large fraction of the overall silicon area and power consumption in modern SoC(s). While embedded memories are typically realized with SRAM, alternative solutions, such as embedded dynamic memories (eDRAM), can provide highe ...

Accelerators for Data Processing

Yusuf Onur Koçberber

The explosive growth in digital data and its growing role in real-time analytics motivate the design of high-performance database management systems (DBMSs). Meanwhile, slowdown in supply voltage scaling has stymied improvements in core performance and ush ...

Single event upset mitigation in low power SRAM design

Adam Shmuel Teman

Logic compatible gain cell (GC)-embedded DRAM (eDRAM) arrays are considered an alternative to SRAM due to their small size, nonratioed operation, low static leakage, and two-port functionality. However, traditional GC-eDRAM implementations require boosted ...

BuMP: Bulk Memory Access Prediction and Streaming

Babak Falsafi, Boris Robert Grot, Stavros Volos, Javier Picorel Obando

With the end of Dennard scaling, server power has emerged as the limiting factor in the quest for more capable datacenters. Without the benefit of supply voltage scaling, it is essential to lower the energy per operation to improve server efficiency. As th ...

Impact of body biasing on the retention time of gain-cell memories

Andreas Peter Burg, Adam Shmuel Teman, Pascal Andreas Meinerzhagen

Gain-cell-based embedded dynamic random-access memory (DRAMs) are a potential high-density alternative to mainstream static random-access memory (SRAM). However, the limited data retention time of these dynamic bitcells results in the need for power-consum ...

Using Managed Runtime Systems to Tolerate Holes in Wearable Memories

James Richard Larus

New memory technologies, such as phase-change memory (PCM), promise denser and cheaper main memory, and are expected to displace DRAM. However, many of them experience permanent failures far more quickly than DRAM. DRAM mechanisms that handle permanent fai ...
