BreakHammer: Enhancing RowHammer Mitigations by Carefully Throttling Suspect Threads
Oğuzhan Canpolat, A. Giray Yağlıkçı, Ataberk Olgun +5
RowHammer is a major read disturbance mechanism in DRAM where repeatedly accessing (hammering) a row of DRAM cells (DRAM row) induces bitflips in other physically nearby DRAM rows.…

CoMeT: Count-Min-Sketch-based Row Tracking to Mitigate RowHammer at Low Cost
F. Nisa Bostanci, Ismail Emir Yuksel, Ataberk Olgun +5
We propose a new RowHammer mitigation mechanism, CoMeT, that prevents RowHammer bitflips with low area, performance, and energy costs in DRAM-based systems at very low RowHammer th…

Spatial Variation-Aware Read Disturbance Defenses: Experimental Analysis of Real DRAM Chips and Implications on Future Solutions
Abdullah Giray Yağlıkçı, Yahya Can Tuğrul, Geraldo F. Oliveira +4
Read disturbance in modern DRAM chips is a widespread phenomenon and is reliably used for breaking memory isolation, a fundamental building block for building robust systems. RowHa…
