HBM Chain Explodes: Nan Ya Ke, Winbond, T-Creative, ADATA, and Kinmax Fully Analyze the Momentum

By the end of April 2026, Taiwan’s memory and HBM-related stocks collectively erupted. Nanya Technology (2408) entered NVIDIA’s Vera Rubin supply chain, and its share price hit the daily limit after jumping sharply. This also pushed up Taiwan’s Google Trends most-searched terms, with “2408,” “high-bandwidth memory,” “Nanya Chip,” “G-Semicon,” and “Winbond” climbing one after another. This article summarizes the core drivers behind this round of HBM/DRAM gains and the specific benefit pathways for Taiwan suppliers, so readers can understand each company’s position in the supply chain at a glance.

Core logic: AI servers consume 66% of global DRAM capacity

This round of momentum is driven by the explosive demand from AI accelerators for HBM (high-bandwidth memory). HBM uses stacked DRAM packaging, and both the per-chip capacity and bandwidth are far higher than those of traditional DDR5. It is a standard configuration for accelerators such as NVIDIA H100/H200/Blackwell/Vera Rubin. After AI servers absorb about 66% of global DRAM capacity, DDR5, LPDDR, and niche DRAM all move into a structural shortage—this is also the fundamental reason consumer memory prices are rising against the trend.

Nanya Technology (2408): Standard DRAM, just entered the Vera Rubin supply chain

Nanya Technology focuses on standard DRAM. At the end of April 2026, reports emerged that it has entered the supply chain for NVIDIA’s next-generation Vera Rubin platform, making it the first Taiwan-listed company to be included. Investment firms estimate that Nanya’s EPS will triple to the NT$21 range in 2026, and reach NT$17 in 2027, reflecting earnings leverage from AI-driven procurement. The 10-nanometer-class (1B) process mass-production progress is a key point to watch—whether it can break into the DDR5 mainstream market will determine its future pricing power.

Winbond (2344): Niche DRAM + edge AI LPDDR

Winbond’s product mix leans toward niche memory (Specialty DRAM) and NOR Flash, with a focus on automotive, industrial control, and IoT. This round’s benefits come from AI PCs and AI phones demanding high-performance, low-power LPDDR, while Winbond’s penetration in edge AI devices is increasing. The market views it as a “secondary beneficiary that doesn’t directly consume HBM, but is boosted by displacement effects.”

Module makers: ADATA (3260), AdataX (4967), Transcend, Apacer

Memory module makers have a very high share of advanced applications in gaming, servers, and enterprise storage. When original equipment manufacturers (Nanya Technology, Micron, SK hynix, Samsung) prioritize shifting capacity to HBM, module makers face increased cost pressure for ordinary DRAM chips. However, this shows up as faster price increases on the sales side and an expansion in gross margin. ADATA and AdataX have continued to see their revenue mix from high-end gaming modules rise this quarter.

Upstream silicon wafers: Globalwafers, G-Semicon

HBM and DRAM capacity expansions both require 12-inch silicon wafers. After Nanya Technology entered NVIDIA’s Vera Rubin, the silicon-wafer supply side—Globalwafers (5483) and G-Semicon (6182)—also benefits in parallel. The characteristic of this supply chain is “capex kick-off → wafer demand rises → capacity becomes tight,” and this quarter G-Semicon’s operating momentum is clearly heating up.

Observation points for SK hynix and Samsung

Among the three major Korean DRAM makers, SK hynix stands out for issuing an approximately NT$30 million-per-person bonus in 2026 due to its HBM leadership, reflecting strong AI cash generation. By comparison, Samsung has once again reportedly been hit by factory strikes this month (Google Trends 4/27 shows searches for “Samsung strike”). The internal labor dynamics of the two Korean giants will directly affect the global HBM and DDR5 supply schedule, and indirectly lift Taiwan suppliers’ room to fill.

Not a bubble: business-cycle swings and AI structural demand coexist

Memory is fundamentally a highly cyclical sector, but the difference between this round and 2017 and 2021 is that “AI structural demand” and the “DRAM displacement effect” are operating along two axes at the same time. The next observation points are the Q1 26 financial reports of SK hynix, Micron, and Samsung (to be released in early May), and whether NVIDIA’s Vera Rubin actual ramp-up timetable continues into the first half of 2027. For Taiwan suppliers, at least, this wave of momentum should last until the third-quarter earnings to provide clear confirmation/a pullback signal.
