Samsung Ships First 12-Layer HBM4E Samples to Customers

Samsung said it has begun sample shipments of a 12-layer HBM4E product to global customers and plans to move into mass production in line with customer schedules after optimization work. The company positions the part as a step beyond its earlier HBM4 rollout, with stated bandwidth up to 3.6TB/s per stack, a stable 14Gbps pin speed scalable to 16Gbps, and a 48GB 12-layer configuration. Samsung also said it may add 32GB and 64GB variants depending on customer demand. For the memory market, the announcement reinforces that leading suppliers are pushing HBM density, performance, and thermal efficiency to support AI infrastructure builds. That does not immediately change commodity DRAM pricing, but it supports firm conditions in advanced memory segments tied to accelerator and hyperscale deployments.
