Samsung Develops 8-Layer HBM4E to Meet Nvidia NVHBM Specs at 17-18Gbps
Samsung Electronics is developing an 8-layer HBM4E product tailored to Nvidia's custom high-bandwidth memory requirements, with a target speed of 17-18Gbps, about 20% faster than its earlier 14.4Gbps sample. The lower stack height suits Nvidia's NVLink-optimized NVHBM, which also requires a logic-based base die that Samsung can supply in an integrated manner.
Samsung Electronics is developing an 8-layer HBM4E product that meets Nvidia's requirements for customized high-bandwidth memory. Compared with the initially planned 12-layer and 16-layer versions, the 8-layer design features a reduced stack height. Nvidia's target speed specification is 17-18Gbps, roughly 20% higher than the 14.4Gbps of Samsung's earlier HBM4E sample.
The 8-layer design is built specifically for Nvidia's publicly disclosed NVLink-optimized NVHBM. NVHBM requires both DRAM and a logic-chip-based base die, and Samsung Electronics can provide both types of production capability in an integrated manner. Nvidia's next-generation AI GPU, Rubin Ultra, is scheduled for launch in 2027, with the number of inter-GPU connections expanding from a maximum of 72 to 576.
