Ready For Next-Gen AI Data Center Superchips, Rambus Intros HBM4E Memory Controller As expected, Rambus has developed the world's fastest HBM4E memory controller, offering a 60% boost over its HBM4 controller with up to 16 Gbps pin speeds (vs 10 Gbps on HBM4) and up to 4.1 TB/s of total bandwidth per module (vs 2.56 GB/s on HBM4). The HBM4E standard will be utilized by NVIDIA's Rubin Ultra GPUs and AMD's MI500 series accelerators.

Press Release: Rambus, a premier chip and silicon IP provider making data faster and safer, today announced the industry’s leading HBM4E Memory Controller IP, extending its market leadership in HBM IP. This new solution delivers breakthrough performance with advanced reliability features enabling designers to address the demanding memory bandwidth requirements of next- generation AI accelerators and graphics processing units (GPUs).

Built on a proven track record of over one hundred HBM design wins to ensure first-time silicon success. Delivers up to 16 Gigabits per second per pin at low latency to meet the demands of next-generation AI and High-Performance Computing (HPC) workloads Expands industry-leading silicon IP portfolio of high-performance memory solutions Rambus HBM4E Controller IP Features:

The Rambus HBM4E Controller enables a new generation of HBM memory deployments for cutting-edge AI accelerators, graphics, and HPC applications. The HBM4E Controller is capable of supporting operation up to 16 Gigabits per second (Gbps) per pin, providing an unprecedented throughput of 4.1 Terabytes per second (TB/s) to each memory device.

For an AI accelerator with eight attached HBM4E devices, this translates to over 32 TB/s of memory bandwidth for next-generation AI workloads. The Rambus HBM4E Controller IP can be paired with third-party standard or TSV PHY solutions to instantiate a complete HBM4E memory subsystem in a 2.5D or 3D package as part of an AI SoC or custom base die solution.

The Rambus HBM4E Controller IP is the latest addition to the Rambus leading-edge portfolio of digital controller solutions. The HBM4E Controller is available for licensing, and early access design customers can engage today.
