Micron Technology, Inc. (MU) vs Taiwan Semiconductor Manufacturing Company Limited (TSM)

Micron Technology is one of the world’s largest semiconductor companies, focused on memory and storage chips. Its main source of revenue comes from dynamic random access memory (DRAM), while it also maintains smaller exposure to NAND flash memory. Micron serves a global customer base, supplying chips for data centers, mobile devices, consumer electronics, as well as industrial and automotive applications. The company operates as a vertically integrated business.

Taiwan Semiconductor Manufacturing Co. (TSMC) is the world’s largest pure-play semiconductor foundry, holding roughly 70% market share in 2025. Founded in 1987 as a joint venture between Philips, the Taiwan government, and private investors, the company listed in Taiwan in 1994 and later launched its US ADR in 1997. TSMC’s vast scale and advanced manufacturing capabilities support strong operating margins, even within the highly competitive foundry industry. The ongoing shift toward the fabless semiconductor model has also provided meaningful growth tailwinds. Its distinguished customer base includes Apple, AMD, and Nvidia, which rely on TSMC’s leading-edge process technologies for their chip designs. The company employs more than 83,000 people.
