Samsung unveils zHBM memory with 8x HBM5 performance

Samsung Electronics unveiled a series of next-generation memory concepts at the Future of Memory and Storage (FMS) 2026 conference in Santa Clara, California, on August 5, 2026. The showcase centered on a new architecture called zHBM, designed to dramatically accelerate artificial intelligence computing by stacking memory directly on top of AI processors.

The zHBM concept represents a fundamental shift from conventional high-bandwidth memory (HBM) designs, where memory chips are placed alongside processors. By vertically stacking HBM above the AI accelerator, Samsung aims to minimize the physical distance data must travel. The company stated this architectural change is intended to deliver up to eight times the performance of the forthcoming HBM5 standard, while also tripling energy efficiency and reducing thermal resistance by more than half. Advanced wafer bonding technology could enable more than ten times the memory density of HBM5.

Alongside zHBM, Samsung introduced zNANDO, a high-performance NAND concept built on its VNAND technology and optimized for edge AI environments. It is designed to offer high space efficiency, improved input/output performance, and low latency for...
