Brief Web Articles on Rowhammer
- If you need help with Rowhammer, watch my background on DRAM and Rowhammer. Many other videos online provide background on Rowhammer (for example, check out Prof. Mutlu's lectures).
- Rowhammer terminology cheat sheet. Academics and DRAM industry both use a variety of terms when it comes to Rowhammer, row disturbance, and DRAM terminology. I put together a list of terms and I did my best to provide a definition for them.
DRFM (Directed Refresh Management). A new DDR5 command that can let a memory controller implement a decent form of Rowhammer protection.
On setting thresholds for counter-based Rowhammer defenses. A class of Rowhammer defenses use counters to track the number of activations a DRAM row receives. When a counter reaches a threshold value, a remedy is performed.
Some folks are surprised to learn that these thresholds must be set conservatively, to very low values, lower than a MAC.
To explain, I wrote a short note on how to set thresholds for counter-based Rowhammer defenses.
