Signal Samsung Unveils V10 BV-NAND and zHBM Memory Architectures at FMS 2026

Summary

Samsung Electronics unveiled its next-generation 3D memory vision at the Future of Memory and Storage (FMS) 2026 conference in Santa Clara on August 5, 2026, according to Samsung Semiconductor's official announcement. The V10 BV-NAND is a prototype featuring more than 400 layers using a new wafer-bonding architecture, lifting bit density about 58% over V9 NAND. zHBM (zero-gap HBM) presents a new architecture vertically stacking HBM directly above AI accelerators rather than positioning it alongside the processor, minimizing data travel distance to improve bandwidth and power efficiency; a next-generation interface system incorporating zHBM is expected to deliver roughly eight times the performance of HBM5, with Samsung claiming four times the data transfer speed of HBM4 at a quarter of the power. Samsung also introduced zNAND-O, a next-generation high-performance NAND solution optimized for edge AI environments requiring real-time, data-intensive processing. All three technologies target the shared problem of AI accelerators sitting idle while waiting for data to arrive.
