Samsung announced three next-generation memory technologies at the Future of Memory and Storage (FMS) 2026 conference: zHBM for stacking HBM directly atop AI accelerators, zNAND-O for bonding NAND to logic devices, and BV-NAND (10th Generation V-NAND) for 3D NAND arrays with integrated control circuitry. All three rely on advanced wafer bonding and are designed to address bandwidth, latency, power efficiency, and thermal challenges in AI data centers.

  • Samsung's three technologies (zHBM, zNAND-O, BV-NAND) all use wafer bonding to integrate memory closer to logic, reducing latency and power consumption in AI systems.
  • zHBM stacks HBM directly atop AI accelerators rather than on peripheral interposers, potentially addressing cooling and power delivery challenges.
  • Samsung claims zHBM delivers 8x performance, 10x memory density, 3x better energy efficiency, and 50% lower thermal resistance versus HBM5, but specifications remain vague.
  • The technology represents continuation of industry efforts to integrate HBM vertically as 2,048-bit interfaces make traditional interposer connections impractical.

How it unfolded

  1. Analysis In-depth technical analysis of zHBM claims

    Coverage notes that Samsung's performance claims about zHBM—including 8x performance and 10x memory density versus HBM5—are vague and lack precise specifications about whether improvements refer to bandwidth, application performance, or other metrics.

    “While Samsung's claims about the zHBM look incredibly impressive, they are vague. For example, when the company claims that a 'next-generation interface system incorporating zHBM' will deliver 'approximately eight times the performance of…”

  3. Event Samsung announces three memory technologies at FMS 2026

    Samsung presents zHBM, zNAND-O, and BV-NAND at the Future of Memory and Storage conference, all utilizing wafer bonding as a common technical foundation.

What people are saying verbatim

“Samsung's zHBM appears to be a continuation of that effort.”

Tom's Hardware, Technical publication · Tom's Hardware ↗ · Aug 7

“Samsung's zHBM concept places HBM directly on top of an AI accelerator instead of on its perimeter, which greatly reduces the distance data must travel between compute and memory.”

Tom's Hardware (citing Samsung), Technical publication · Tom's Hardware ↗ · Aug 7

“This architecture can increase bandwidth and power efficiency and projects that it can provide 8x the 'performance of HBM5', while its advanced wafer bonding is expected to enable over 10x higher memory density, 3x better energy efficiency, and more than 50% lower thermal resistance than HBM5.”

Samsung, Memory manufacturer · Tom's Hardware ↗ · Aug 7

“Had Samsung intended to compare raw bandwidth, it would likely have used more precise wording, such as '8x higher bandwidth.' Instead, the general term 'performance' may have many meanings.”
