DRAM vs SMH vs SOXX: Which Semiconductor ETF Fits Your Thesis?
DRAM owns only memory chips. SMH owns the full semiconductor supply chain globally. SOXX owns U.S.-focused chip companies with diversified weighting. Three different bets on the same industry.
🧠 Memory vs. broad chip exposure
💰 Cost, AUM, and track record
⚠️ Risk and concentration
🧠 Why DRAM is getting searched 1,700% more than last year
The Roundhill Memory ETF (ticker: DRAM) launched in 2024 and has surged in search interest as investors connect the AI hardware buildout to memory chip demand. Nvidia's data center GPUs require High Bandwidth Memory (HBM), and only Micron, SK Hynix, and Samsung make it at scale. DRAM is the only fund dedicated entirely to those companies. That specificity is the entire thesis.

The BFF Take
SMH is the default answer for semiconductor exposure. 26 holdings, 0.35%, 24-year track record, global coverage. If you believe in chips broadly, start here. SOXX is the U.S.-centric alternative at the same cost with slightly more even weighting. The choice between them is close. DRAM is a different decision: it is a concentrated, cycle-dependent bet on memory specifically. The AI HBM thesis is real and the 1-year returns reflect it. So does the 0.75% expense ratio and the thin AUM. DRAM belongs in a satellite position, not a core holding. If the memory cycle turns, DRAM will demonstrate that very clearly.
Who Each Fund Is Built For
DRAM
Best for
- Investors with a specific AI HBM thesis
- Deliberate overweight to memory over logic chips
- Satellite position (5-10% of portfolio max)
- Short-to-medium time horizon on the memory cycle
SMH
Best for
- Default semiconductor sector exposure
- Global chip supply chain in one fund
- Long-term core semiconductor holding
- Investors who want TSMC and ASML included
SOXX
Best for
- US-focused semiconductor exposure
- More even weighting (10% single-stock cap)
- Long-term core semiconductor holding
- Preference for domestic over global chip exposure
Frequently Asked Questions
What is the difference between DRAM, SMH, and SOXX?
DRAM holds only memory semiconductor companies: Micron, SK Hynix, Samsung, SanDisk/WD. SMH holds the 26 largest semiconductor companies globally: chip designers (Nvidia, AMD), manufacturers (TSMC), and equipment makers (ASML) alongside memory. SOXX holds ~30 US-focused semiconductor companies with a 10% cap per holding. DRAM is the narrowest and most expensive. SMH and SOXX are broader, cheaper, and cover the full semiconductor supply chain.
Is DRAM ETF a good investment?
DRAM is a high-conviction, high-risk bet on the memory semiconductor cycle. The fund's thesis centers on AI data center demand for High Bandwidth Memory (HBM) in GPU packaging. That thesis has driven strong recent returns. The risks: memory is one of the most cyclical sectors in semiconductors, DRAM charges 0.75% versus 0.35% for SMH or SOXX, and the fund has a very short track record. It is not a core holding for most investors. Past performance does not guarantee future results.
Should I choose SMH or SOXX for semiconductor exposure?
Both charge 0.35% and cover semiconductors broadly. SMH holds 26 stocks, allows up to 20% in a single name (often Nvidia or TSMC), and includes significant international exposure. SOXX holds 30 US-focused companies with a 10% cap, resulting in slightly more even diversification. SMH has historically outperformed due to higher concentration in the largest chip names. SOXX's US focus appeals to investors who prefer domestic exposure. Either is a reasonable default.
Can I hold DRAM alongside SMH or SOXX?
Yes, but understand what it does: holding DRAM alongside SMH increases your exposure to memory chip companies, which are already a component of SMH. You are concentrating further in memory at the cost of the chip designer and equipment diversification that SMH provides. Some investors do this deliberately to overweight the HBM/AI memory theme. It is an intentional bet, not additional diversification.
Past performance does not guarantee future results. Fund data is approximate and may not reflect current holdings or returns. DRAM is a new fund with a limited track record.
