The Roundhill Memory ETF (DRAM) has achieved rapid growth, surpassing $25 billion in assets within four months of its April 2, 2026 launch, positioning it as a significant player in the thematic ETF space. The ETF's strategy focuses on memory chips, a sector benefiting from increased demand tied to artificial intelligence infrastructure.
DRAM's portfolio is highly concentrated, with Samsung Electronics (24.99%), SK Hynix (24.22%), and Micron Technology (23.83%) accounting for approximately 73% of its holdings. This structure presents investors with a potent, albeit focused, bet on the memory market's performance. Geographically, the fund is weighted towards South Korea (49.25%) and the United States (37.65%).
For investors seeking exposure to the memory chip sector, alternative avenues exist. Micron Technology (NASDAQ:MU) has outperformed DRAM on a percentage basis since the ETF's inception, returning 162.86% compared to DRAM's 107.78% gain. Broader semiconductor ETFs like the VanEck Semiconductor ETF (SMH) and the iShares Semiconductor ETF (SOXX) also offer diversification within the chip industry, though they trail Micron's individual performance.

AI memory chips
A new fund focused on computer memory chips has grown very large very fast because artificial intelligence needs lots of memory. However, because the fund puts most of its money into only three companies, it can be very risky if those companies struggle.
What changed
The Roundhill Memory ETF (DRAM) crossed $25 billion in assets four months after launch, highlighting extreme investor demand for specialized AI memory hardware.
Who wins / who loses
Memory chip makers and specialized ETFs win big from AI infrastructure spending, while diversified investors face heightened single-sector concentration risk.
