How to Configure Row-Sampling-Based Rowhammer Defenses

2nd Workshop on DRAM Security (DRAMSec) |

Row-Sampling is a simple, practical, and strong form of Rowhammer defense if properly configured. Unfortunately, previous papers either omit describing how to configure Row-Sampling, or when they do, their formulae suffer from limitations and unrealistic assumptions. This paper presents a mathematically rigorous description of how to configure Row-Sampling to protect an entire system for a given period of time
