At the Future Memory & Storage conference in Santa Clara on Aug. 4, Samsung
Electronics introduced a V10 Bonding V‑NAND (BV‑NAND) prototype with more than
400 layers using a new wafer‑bonding architecture. Samsung says BV‑NAND
increases storage density about 58% versus its V9 NAND while improving read,
write and I/O performance to address AI system demand for higher‑capacity, more
energy‑efficient memory. The company also presented concept models for zHBM and
zNAND‑O that vertically stack memory on top of AI accelerators rather than
beside them, shortening data paths, boosting bandwidth and improving power
efficiency. Samsung says its wafer‑bonding approach could deliver more than 10x
the density of conventional HBM5, roughly 3x the energy efficiency and over 50%
lower thermal resistance.
