Enabling Efficient and Scalable DRAM Read Disturbance Mitigation via New Experimental Insights into Modern DRAM Chips

Abdullah Giray Yağlıkçı

Increasing storage density exacerbates DRAM read disturbance, a circuit-level vulnerability exploited by system-level attacks. Unfortunately, existing defenses are either ineffecti…

An Experimental Characterization of Combined RowHammer and RowPress Read Disturbance in Modern DRAM Chips

Haocong Luo, Ismail Emir Yüksel, Ataberk Olgun +3

DRAM read disturbance can break memory isolation, a fundamental property to ensure system robustness (i.e., reliability, security, safety). RowHammer and RowPress are two different…

RowPress Vulnerability in Modern DRAM Chips

Haocong Luo, Ataberk Olgun, A. Giray Yağlıkçı +6

Memory isolation is a critical property for system reliability, security, and safety. We demonstrate RowPress, a DRAM read disturbance phenomenon different from the well-known RowH…

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…
