The best-performing way to play the chip boom in 2026 has not been Nvidia (NASDAQ: NVDA), Advanced Micro Devices (NASDAQ: AMD), or Broadcom (NASDAQ: AVGO).
It has been a small, brand-new fund built around the one corner of semiconductors that giants can’t live without: memory
The Roundhill Memory ETF (NYSEMKT: DRAM) has roughly doubled since it launched this spring, outrunning all three AI chip stars, and the reason comes down to a technology most investors ignore. What DRAM is, and why it became the AI bottleneck DRAM, or dynamic random-access memory, is a computer’s short-term working memory, the place a chip keeps the data it is actively crunching. For decades, it was a sleepy commodity.
AI flipped that on its head. Running and training large models means moving colossal amounts of data at high speed, which has created frantic demand for a premium form of DRAM called high-bandwidth memory, or HBM. HBM is DRAM stacked in layers and placed right beside the AI processor so information flows almost instantly.
