Building Practical Rowhammer Protection into Azure Cobalt 200 (opens in new tab)

As memory becomes central to cloud and AI infrastructure, so is the need to protect against memory-based vulnerabilities and attacks at cloud scale. With Azure Cobalt 200, Microsoft’s second-generation Arm-based compute processor, we took the opportunity to re-think how to deliver advanced memory security defenses through deep hardware-software codesign, leveraging all parts of the system design, including silicon, platform, firmware and telemetry. Rowhammer and the Need for End-to-End Memory...
