About AI Nodelab

AI NodeLab is an independent English-language blog about AI memory, semiconductors, and the Korean companies helping build the infrastructure behind modern AI.

A faster memory chip or a more efficient model can make a promising headline. The harder question is what it changes in a working system. This blog looks at those practical consequences: where data is stored, how it moves, what limits performance, and which trade-offs remain.

A Korean perspective on AI infrastructure

I write from Korea, with a professional background in the semiconductor industry. My focus is on connecting technical developments with Korea’s role in the wider AI supply chain—from Samsung and SK hynix to Korean model developers and their deployment choices.

That perspective does not mean assuming every advance benefits Korean companies. I look for the conditions that would make a technology useful, the evidence still missing, and what would need to happen before an announced plan becomes a commercial result.

What you will find here

• Explanations of HBM, DRAM, NAND, advanced packaging, and AI memory systems.
• Practical breakdowns of inference, KV cache, quantization, and model memory requirements.
• Analysis of Korean companies and technologies in the context of global competition.
• Worked examples and comparisons that help readers evaluate technical claims for themselves.

Sources and editorial approach

Articles draw on publicly available sources, including technical documentation, research papers, company disclosures, and official announcements. Company targets are distinguished from shipping products and independently demonstrated results. Calculations include their assumptions so readers can understand where the numbers apply—and where they do not.

AI tools assist with research, drafting, and English-language editing. I review the material before publication and take responsibility for the published content. Interpretations and forecasts are presented as judgments, not established facts.

I do not publish confidential employer information. The views expressed here are my own and do not represent any employer or company discussed.

Corrections and contact

Technical information changes, and mistakes can happen. If you find an error or a source that changes an article’s conclusion, please use the Contact page and include the article title, the relevant passage, and a supporting source where possible.

AI NodeLab provides educational information and analysis, not personalized investment advice. A company’s involvement in a technology does not, by itself, establish an investment opportunity.
