Samsung Mass Produces and Ships 24Gbps HBM4 Memory with 64GB Stacks
Samsung has commenced mass production of its HBM4 memory chips, delivering speeds up to 24Gbps per pin and stack capacities reaching 64GB optimized for AI workloads. Initial shipments have started, potentially bolstering Nvidia’s supply of high-bandwidth memory for next-gen GPUs.
1. Mass Production of HBM4 Memory
Samsung has begun mass production of its fourth-generation high-bandwidth memory (HBM4) at its advanced fabrication facilities. These chips deliver per-pin data rates up to 24Gbps and support up to 64GB per stack, targeting AI accelerator and GPU workloads.
2. Initial Shipments and Nvidia Supply
The first HBM4 shipments are now underway, with allocation expected to flow to major GPU makers. This ramp could ease Nvidia’s memory constraints for its next-generation graphics and AI processors, improving throughput and potentially reducing unit costs.
