SpyHammer: Understanding and Exploiting RowHammer under Fine-Grained Temperature Variations

Lois Orosa, Ulrich Rührmair, A. Giray Yaglikci +7

RowHammer is a DRAM vulnerability that can cause bit errors in a victim DRAM row solely by accessing its neighboring DRAM rows at a high-enough rate. Recent studies demonstrate tha…

HiRA: Hidden Row Activation for Reducing Refresh Latency of Off-the-Shelf DRAM Chips

Abdullah Giray Yağlıkçı, Ataberk Olgun, Minesh Patel +5

DRAM is the building block of modern main memory systems. DRAM cells must be periodically refreshed to prevent data loss. Refresh operations degrade system performance by interferi…

Understanding RowHammer Under Reduced Wordline Voltage: An Experimental Study Using Real DRAM Devices

A. Giray Yağlıkçı, Haocong Luo, Geraldo F. de Oliviera +7

RowHammer is a circuit-level DRAM vulnerability, where repeatedly activating and precharging a DRAM row, and thus alternating the voltage of a row's wordline between low and high v…

A Case for Transparent Reliability in DRAM Systems

Minesh Patel, Taha Shahroodi, Aditya Manglik +4

Today's systems have diverse needs that are difficult to address using one-size-fits-all commodity DRAM. Unfortunately, although system designers can theoretically adapt commodity…
