## Is there a memory and storage ETF?

Yes. ETFIQ covers 5 memory and storage ETFs as of Oct 20, 2026. The largest is DRAM at $18.6bn. The cheapest is DRAM at 0.65%.

How much of a memory and storage fund is already in the S&P 500 decides how much of it is new exposure. Across these 5 funds the median is 29.1% of the weight. The rest is what you are buying that an index fund does not already hold.

Concentration is the other thing to read. The median memory and storage ETF here holds 59.2% of its weight in its top ten positions. That is what a theme fund does: it buys a shortlist, not a market.

ETFIQ files a fund under a theme editorially, from what the fund holds rather than from its name, and every figure on this page is the one its memory and storage hub prints.
