Methodological study on paradigm shift in DRAM row hammer defense system

Abstract

In 2014, the revelation of low hammer attacks spurred active research. Focused initially on hardwarebased defenses, these efforts faced issues like increased power usage and hardware size. This work introduces a new, more efficient low hammer defense system, leveraging a DRAM standard called Refresh Management (RFM) to address these challenges. We propose a module to detect attacks and efficiently use RFM, improving defense and minimizing power consumption.
