**Citable summary**: Phison Electronics's confirmed suppliers/cost counterparties include TSMC, Micron Technology, 키옥시아. Per the valuechain.wiki graph: 3 cost edges, backed by 4 dated sources, 1 of them primary filings (as of 2026-07-12).

### TSMC (high)  → /tsmc.md
- note: Outsources NAND controller chips to TSMC and others as a fab-lite maker — foundry capacity and node access drive product launches and cost.
- [confirms] DigiTimes (EN, news, published 2026-03-08) https://www.digitimes.com/news/a20260308PD200/phison-2026-growth-2025-nand-flash.html: "Manufactures NAND controller chips at TSMC and others."
- [confirms] Phison (EN, filing, published 2025-07-08) https://www.phison.com/en/investor/financial-information: "Manufactures NAND controller chips at TSMC and others."

### Micron Technology (high)  → /micron.md
- note: One of Phison's NAND wafer sources. Phison buys about 16EB of raw NAND per year at wafer level across major suppliers (Kioxia/WD, Micron, Samsung, SK hynix/Solidigm, YMTC).
- [confirms] Blocks and Files (EN, news, published 2023-06-12) https://blocksandfiles.com/2023/06/12/phison-largest-ssd-supplier-no-one-knows-about/: "Original design partner for the main NAND suppliers; Phison buys 16 exabytes of raw NAND a year at wafer level."

### 키옥시아 (mid)  → /kioxia.md
- note: Sources NAND flash for SSDs from Kioxia and others — as NAND is most of SSD cost, the NAND price cycle is the biggest cost variable driving margin.
