Canonical title: BreakHammer: Enabling Scalable and Low Overhead RowHammer Mitigations via Throttling Preventive Action Triggering Threads
Question: Can RowHammer defenses reduce their own performance/energy cost by slowing the threads that trigger preventive actions?
Context: Existing mitigations protect rows globally, so one aggressive or malicious thread can impose refresh/repair overhead on all workloads.
Method: BreakHammer monitors preventive-action attribution, identifies suspect threads, and throttles their memory bandwidth.
Evaluation: workloads=eight RowHammer mitigation mechanisms; baselines=each mitigation without BreakHammer; metrics=performance; DRAM energy; fairness; area; results=improves all evaluated mitigations; near-zero area overhead
Interpretation: Attributing defense cost to its trigger lets the system contain both attacks and collateral overhead.
Reusable lesson: Add per-principal attribution and feedback throttling around expensive shared defenses.
Applicability: DRAM systems deploying preventive RowHammer mitigations.
Limits: Relies on correct culprit identification and simulated mitigation models; benign high-activity threads can be throttled.
