What it is

Samsung is the world's largest overall memory maker (DRAM + NAND) but fell behind SK Hynix in HBM, spending much of 2024-2025 working through Nvidia's HBM3E qualification while supplying HBM to AMD and others. It uses a TC-NCF stacking approach and its scale in commodity DRAM/NAND gives it leverage, but AI-memory leadership has been the strategic prize it is chasing via HBM4 and a captive foundry that can build its own logic base die. Samsung uniquely spans memory, logic foundry (samsung-foundry), and packaging under one roof.

Times are New York time. Free sources are pulled on the schedule shown by the pipeline runner (data/corpus/run_pipelines.py), which logs every run; paid sources run only with the owner's yes; filings and newsroom pages are re-read when a new document is filed.

Links come from the AI Systems Map ontology. Deals carry the filing's own wording and a quote, checked against the document; latest source 2026-10-26. Not investment advice.
