Zentel's new DDR3 DRAM has published data showing zero Row Hammer failures. I fondly recall talking to a large vendor’s ‘tiger team’ concerning Row Hammer failures a few years back. I asked them what should their DDR3 users do if they start to experience Row Hammer failures. Their response? ‘Upgrade to DDR4!’. ‘How convenient’ I responded, ‘forcing the industry to throw away all those DDR3 based systems so you can sell more DDR4’. And come to find out, DDR4 although a bit better, still experienced Row Hammer failures!
We here at FuturePlus Systems are glad to see our colleagues in academia are still hunting down those Row Hammer vulnerabilities (https://rambleed.com/). They can feel good about causing the industry to look for solutions, and it appears that Zentel has answered the call.
