Memory-Centric Computing: Security Benefits and Challenges of Processing-in-DRAM
Ismail Emir Yuksel, F. Nisa Bostanci, Ataberk Olgun +1
Today's computing systems are processor-centric: they require frequent data movement between processing elements (e.g., CPU) and main memory (DRAM), leading to significant ineffici…
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…
ABACuS: All-Bank Activation Counters for Scalable and Low Overhead RowHammer Mitigation
Ataberk Olgun, Yahya Can Tugrul, Nisa Bostanci +6
We introduce ABACuS, a new low-cost hardware-counter-based RowHammer mitigation technique that performance-, energy-, and area-efficiently scales with worsening RowHammer vulnerabi…
