Reducing HBM ECC Controller Overhead For AI Inference (RPI, IBM)

Researchers at Rensselaer Polytechnic Institute and IBM T.J. Watson Research Center published a technical paper titled “REACH: Controller-Managed Long-Span ECC for HBM AI Inference.” Abstract Excerpt: “High-Bandwidth Memory (HBM) cost motivates stronger controller protection that can support a wider range of device error rates.High-Bandwidth Memory (HBM) cost motivates stronger controller protection that can support a wider range of device error rates. Long-span error-correcting codes provide st
