Analysis of the 2026 Storage Industry White Paper

I. Market Trends: Officially Entering the "Epic Golden Age"
Leapfrog Growth in Scale: The global memory market is projected to reach $221.6 billion in 2025 (a 33% year-on-year increase), with the potential to exceed $600 billion in 2026.

Seller's Market Established: Memory manufacturers' capacity growth lags behind demand, returning pricing power to the supply side. The price increase trend is expected to persist throughout 2026.

Application Structure Shift: Server demand replaces smartphones as the primary engine. It is projected that server NAND demand will account for 37% in 2026, and server DRAM (including HBM) will exceed 50% for the first time.

II. Core Technology Evolution (NAND & DRAM)
(I) NAND Flash: Evolving Towards High-Layer Stacking and Hybrid Bonding
300+ Layer Era: Products with over 300 layers are accelerating into mass production, with major manufacturers progressing towards 400 layers.

Architectural Innovation: Hybrid Bonding enables decoupled manufacturing of memory arrays and logic circuits, a trend led by Yangtze Memory Technologies' Xtacking architecture.

Increased Parallelism: Mainstream exploration is moving from 4-Plane to 6-Plane (Micron, SK Hynix) and even 8-Plane (Kioxia/SanDisk) to enhance read/write throughput.

QLC Replacing HDD: Due to constrained HDD supply and low willingness for capacity expansion, high-capacity QLC eSSDs (up to 122.88TB/245.76TB per drive) are entering a "golden window" for HDD replacement.

(II) DRAM: Process Nearing Limits and Form Factor Transformation
Process Breakthrough: 1c nm enters mass production, fully embracing EUV lithography.

Form Factor Evolution: LPCAMM2 brings a transformation in notebook memory form factor, reducing volume by 64% with speeds reaching 9600MT/s, offering both high performance and maintainability.

3D DRAM: Manufacturers are beginning to explore 4F² vertical architecture and IGZO materials to address physical limits below 10nm.

Heterogeneous Architecture: NVIDIA is expected to launch a platform integrating an LPU (Language Processing Unit) hardware stack in 2026, leveraging the extreme bandwidth of on-chip SRAM to break the "memory wall."

III. New Storage Paradigm in the AI Era
(I) Synergy of HBM and HBF
HBM4 Arrival: HBM4 will be deployed on flagship accelerator cards in 2026, with single-stack capacity rising to 36-48GB and total bandwidth leaping to 2TB/s.

Rise of HBF (High Bandwidth Flash): To address HBM's capacity bottleneck and high cost, HBF (using NAND as the medium, reusing HBM packaging) has emerged. In terms of performance, read bandwidth is comparable to HBM3E, capacity can exceed 8 times that of HBM, and cost is significantly lower. Commercially, commercialization is expected to start in 2027, with explosive growth from 2028 to 2030.

(II) Edge AI Reshaping Consumer Electronics
AI Phones: Running large models on-device demands high memory bandwidth, making LPDDR5X standard, with 16GB of memory becoming mainstream for flagship phones.

AI PCs: Memory bandwidth replaces compute power as the performance bottleneck. Smoothly running 70B-level models requires over 48GB of memory and bandwidth in the 256GB/s range.

IV. Emerging Application Fields
Smart Cars: In-vehicle storage is upgraded from a simple component to an intelligent core. Storage demand evolves from 8-32GB eMMC to 64GB-TB level UFS 4.1/PCIe solutions.

Smart Wearables: Devices are transforming into "independent intelligent agents." ePOP technology stacks memory and storage vertically, saving 50%-75% of PCB space.

The memory market in 2026 is at a critical juncture of transitioning from "mere storage" to "computing infrastructure." Whether it's the architectural innovation of HBM/HBF or the penetration of QLC in data centers, the core driving force points to the extreme pursuit of high bandwidth, large capacity, and low cost by AI large models.
