Micron’s AI-memory surge pushes MU and tech ETFs into the limelight

Micron Technology crossed the $1 trillion market cap after a 19.3% rally driven by AI-memory demand (HBM for Nvidia and upcoming HBM4/HBM4E), with a $2 billion U.S. plant expansion boosting supply. Rather than buying MU outright, investors may gain MU exposure through tech ETFs like Roundhill Memory (DRAM), IGPT, SOXQ, and SOXX, which allocate MU heavily (about 28% in DRAM and around 9–10% in the others), offering diversified AI-memory upside while mitigating single-stock risk.
