Understanding the Security Benefits and Overheads of Emerging Industry Solutions to DRAM Read Disturbance
Oğuzhan Canpolat, A. Giray Yağlıkçı, Geraldo F. Oliveira +3
We present the first rigorous security, performance, energy, and cost analyses of the state-of-the-art on-DRAM-die read disturbance mitigation method, Per Row Activation Counting (…
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.…
Revisiting Main Memory-Based Covert and Side Channel Attacks in the Context of Processing-in-Memory
F. Nisa Bostanci, Konstantinos Kanellopoulos, Ataberk Olgun +6
We introduce IMPACT, a set of high-throughput main memory-based timing attacks that leverage characteristics of processing-in-memory (PiM) architectures to establish covert and sid…
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…
