Key points
- Macronix's annual ROM chip output has fallen by 39%, and the product now accounts for only 5% of its business.
- The freed capacity is shifting toward NOR, NAND, and eMMC memory production.
- Nintendo may need alternative chip suppliers, potentially raising the cost of physical game cartridges.
Context
Macronix was the principal supplier of ROM chips for Nintendo's physical game media, with Rohm and Lapis Semiconductor identified as remaining alternatives. This does not signal an immediate end to physical cartridges, which Nintendo said it continues to support. Digital games already generated 61.5% of Nintendo's software revenue in the second calendar quarter of 2026.

Who benefits: No one from your readership has an immediate need to act.
