Supporting Rowhammer Research to Strengthen DDR5 Mitigations

🔬 Google funded and collaborated on open-source DDR5 Rowhammer test platforms and academic research to evaluate current in-DRAM mitigations. Working with Antmicro and ETH Zurich, the team produced FPGA-based RDIMM and SO‑DIMM testers and used them to discover the Phoenix attack family, which includes a self-correcting refresh synchronization technique that can bypass enhanced TRR on some DDR5 modules. Google also led JEDEC standardization work on PRAC to enable deterministic row-activation counting and continues to share tools and findings to improve defenses.
