Key Developments & Data
Samsung unveils three next-generation wafer-bonded memory technologies for AI data centers.
Samsung presented its zHBM, zNAND-O, and BV-NAND architectures at the Future of Memory and Storage 2026 conference.
The zHBM design stacks memory directly on top of AI accelerators rather than placing packages on the chip perimeter.
Samsung projects zHBM will provide 8x the performance and 10x higher memory density compared to HBM5.
The company also introduced zNAND-O for edge AI and 400-layer BV-NAND offering I/O speeds up to 5,600 MT/s.
Stacking memory straight onto hot logic dies solves interposer bottlenecks but shifts the entire engineering headache to power delivery and thermals.
