Abstract: DRAM read disturbance, like RowHammer and RowPress, is a critical robustness issue where accessing DRAM can cause unintended bitflips in other unaccessed DRAM locations. DRAM read disturbance bitflips significantly impact the safe, secure, and reliable operation of DRAM-based computing systems. Many prior works experimentally characterize these bitflips and propose mitigations based on empirical results. Other device-level works study their underlying physical mechanisms, but these mechanisms do not fully explain all major empirical observations.

Our goal is to bridge the gap between experimental characterization and device-level modeling and understanding of RowHammer and RowPress, providing a principled foundation for future work on understanding, characterizing, and mitigating DRAM read disturbance.…
