See the full list FREE now.The supply chain shortage in Dynamic Random Access Memory (DRAM), and more specifically, in High Bandwidth Memory (HBM) chips is a big reason why the memory chip "Big 3": SK Hynix, Samsung, and Micron Technology - have all been soaring with triple digit 1-year returns in 2026. The fact that these three companies have a virtual monopoly on the HBM sector, which is integral for A.I. development, has created a bottleneck in the supply chain. Although the South Korean government recently announced a $590 billion investment towards HBM and A.I. related production expansion, the results are not expected to become manifest for another five years in the future, which does nothing to ease supply chain woes in the present day. IntelEnter Taiwan Semiconductor. TSMC is the 800 lb. gorilla of semiconductor manufacturing, being the sole foundry for Nvidia, and AMD, as well as a major supplier for Apple and other technology titans. TSMC just announced a collaboration with Taichung headquartered Winbond to supply DRAM chips and other HBM memory chips for A.I. applications to address the supply bottleneck. ETFs with large positions in TSMC, such as VanEck Semiconductor ETF (NASDAQ: SMH), iShares MSCI Taiwan ETF (NYSE: EWT), and Roundhill Memory ETF (CBOE: DRAM), which holds one of the largest stakes in Winbond among US ETFs, may all be worth watching as further news unfolds.

S.K. Hynix, which is the world's largest HBM supplier at the time of this writing (60% of the global market), recently filed for a $29 billion NASDAQ listing to help it expand to accommodate the backlog on orders, not to help its balance sheet. The TSMC and Winbond collaboration not only offers the market a potential alternative new supplier, but one with an unquestionable pedigree from the A.I. processing side of the fence.
