文章內容提出:
如果 HBM(High Bandwidth Memory,高頻寬記憶體)
持續成為 AI 推理(inference)的主要瓶頸
Micron($MU)有望在 6-12 個月內
從目前約 1 兆美元 市值
快速逼近 Meta 的 1.3-1.4 兆美元。
為什麼 HBM 如此關鍵?
每次 AI 推理都需要 HBM:
不像訓練主要靠 GPU,推理過程高度依賴記憶體。
成本暴增:HBM 已讓成本 of goods 上升 5 倍。
結構性優勢:生產 HBM 的公司,
會獲得類似 GPU 廠商(NVIDIA)
的定價權與高毛利,
但市場目前尚未完全將此
HBM 敘事計入 $MU 估值 → 存在明顯低估。

•NVIDIA halved SOCAMM low-power CPU memory from 192GB to 96GB in next-gen AI servers amid tight supply.
•HBM GPU memory remained untouched while market swung on shortage signals.
•Micron pushes more memory for faster KV cache and inference performance.
•NVIDIA redesigned server for lowest cost and power instead of adding more.
•Buyer optimized memory placement over seller's "more is better" advice.

NVIDIA下一代AI服务器将CPU侧低功耗内存
SOCAMM从192GB减半至96GB,
主要因三星、SK海力士、美光
三家供应商2027年供应能力仅达需求60%,
HBM内存未受影响。
消息引发内存股先跌后涨,
市场对AI内存需求是“冷却”
还是“短缺加剧”意见分歧,
而NVIDIA与Micron在官方材料中
发出相反信号。
Micron强调增加该内存可提升
AI推理KV cache性能
NVIDIA却选择减量
实际是将内存工作负载转移
至其他层级以优化成本和功耗。

Chinese firms (e.g., Jushi) act as the aggressors. They have aggressively expanded capacity, benefited from lower energy costs, and recently outperformed Nittobo (日东纺) in stock performance.
Japanese firms (e.g., Nittobo) are more defensive. They hold strong technological and pricing power but have been constrained by high energy costs and have not raised prices as aggressively.
Key points on NVIDIA and supply chain interdependence:
NVIDIA has made Q-cloth a required material for its upcoming Rubin platform.
Chinese company FIBERHOME (菲利华, 300395) is in the NVIDIA certification process and is one of China’s leading Q-cloth producers. However, it (and the broader Chinese industry) still relies heavily on Japanese precision manufacturing equipment (e.g., from Shin-Etsu Chemical as the top player).
This highlights the deeply intertwined nature of the semiconductor supply chain: “you are in me, I am in you.”
Outlook for Nittobo and the sector:
Nittobo’s catch-up potential hinges on the Strait of Hormuz remaining open, which could ease Japan’s energy bottlenecks (electronic cloth production is highly energy-intensive).
If energy issues are resolved and Nittobo can confidently expand capacity and raise prices, it could see a strong rebound.
In a peaceful East Asia environment, Chinese and Japanese companies together could maintain strong pricing power and profitability.
The author notes that Murakami’s fund was smart to place some capacity in China to avoid Japan’s energy constraints. Overall, the post emphasizes that while the industry has great potential, geopolitical and energy risks remain critical variables.

Taiwanese optics leader Largan Precision is spending NT$650 million (approx. US$20 million) to purchase automation and glass solutions from Chinese laser equipment giant Han’s Laser. The equipment supports Largan’s push into TGV (Through Glass Via) technology for multilayer stacked optical components.
Meanwhile, Chinese optics major Sunny Optical has upgraded its FAU (Fiber Array Unit) team to the level of a full research institute and is planning to establish a dedicated base in Singapore to deepen high-precision FAU R&D.
Both Taiwanese and Chinese first-tier optics giants are now aggressively chasing FAU precision manufacturing as a major future growth driver. This trend is also expected to boost demand for upstream laser automation equipment.

$MU is a typical "forgotten winner" with outstanding cost performance in the current AI cycle. But the market is a voting machine in the short term and a weighing machine in the long term - if $MU continues to deliver more than expected, the valuation convergence is a likely event. Those who want to vote can pay attention to MU's HBM share and quarterly guidelines, while SpaceX is suitable for long-term believers.

Korean Media: SK Hynix Preparing Massive $66.4 Billion Shareholder Return Program Following ADR Listing
- Korean media report that SK Hynix is expected to announce a large-scale shareholder return program worth approximately $66.4 billion after its ADR listing.
- To minimize dilution concerns and potential backlash from existing shareholders, the company has reportedly reduced the ADR offering size from 2.4% of outstanding shares to the low-2% range.
- SK Hynix is expected to raise approximately KRW 40 trillion (about $26.5 billion) through the issuance of new shares as part of the ADR offering.
