AI inference is hitting a memory limit, and CXL switching, which pools memory across servers, is where the value map changes. HBM is costly and limited per chip, and bigger models outgrow one server. Marvell is the bet on switching as the control point, via XConn and Structera S, now in production. Penguin Solutions makes CXL deployable in its KV cache server. Micron's CXL DRAM is a structural tailwind still tied to DRAM cycles, and Credo sits in the competitive transport layer. x.com  x.com  … Show more

The AI memory wall is a structural bottleneck only beginning to be priced in, favoring companies that move data closer to compute. Training wastes about 90% of energy moving data, HBM4 uses 3x DDR5's wafer capacity, and DRAM and NAND spot prices rose 80–90%. Corsair holds DRAM bought at 2025 prices; Penguin's CXL-based MemoryAI server trades near 10–12x forward earnings with near-100% EPS growth; Rambus has HBM4E controllers and 80%-plus gross margins; Sanmina's Viking makes US-built memory. … Show more

Astera Labs carries a huge premium for flawless execution against a CXL market that is small near term. Switch-based CXL memory pooling capturing $15-16B in 2026-2028 is low probability: Marvell guides its XConn switch business to only about $100M by fiscal 2028, PCIe included. Pooling software likely stays immature into 2028, per a Samsung white paper, and Nvidia is contesting the warm KV-cache tier. Astera does CXL best, but SK hynix and Micron offer better risk-adjusted returns. x.com  x.com 

The memory cycle looks set to last longer than expected because Micron is spending as if AI memory demand will run for years. Its capex was $27.4B in FY26 and about $25B in FY27's first half alone, with the second half expected higher, putting $50B+ in play; Micron wouldn't spend this aggressively if it saw the cycle ending next year. AI is consuming huge amounts of DRAM, NAND and HBM, a shortage that also benefits SK hynix, Samsung, SanDisk, Western Digital and Seagate. x.com  x.com  x.com  x.com  … Show more

Penguin Solutions benefits as more AI tightens DRAM and lifts demand for its memory systems, with CXL as a high-beta moonshot. It reaffirmed FY26 revenue and EPS at the high end of guidance, and its CEO says memory and AI infrastructure demand keeps growing. CXL lets GPUs use DRAM pools about 20x cheaper than HBM and 10-100x larger, easing the KV-cache bottleneck in long-context inference. Penguin is the most compelling high-beta CXL bet, though CXL is still tiny for its business. x.com  x.com 

Marvell's management is running the stock as a pump and dump to move shareholders' money into their own pockets. Wall Street prices Marvell as an ASIC design house without realizing that ASIC design is just IT outsourcing. It is not a real CXL play either: CXL IP is sold by Cadence, Synopsys and Rambus with no moat, and Astera Labs, which builds the switches and software around CXL, is the only good CXL play. x.com 

These ten semiconductor stocks look cheap because each has a PEG ratio near or below 1, meaning growth outpaces valuation. Nvidia's Q1 revenue rose 85% and AMD's 38% with MI350 commitments; Broadcom's AI chip revenue rose 143% with a $73B AI backlog; Marvell's custom silicon doubled. Sandisk has $42B in contracted backlog, Micron's HBM is sold out through 2026, and Coherent, Credo and Applied Optoelectronics ride AI optics demand. ON Semiconductor is the slow-growth value play. x.com  x.com  x.com  … Show more

These ten companies span every layer of AI capex, which Goldman sees surging to $1.2 trillion in 2027, so each should make money. Credo, Broadcom, Micron, Nvidia, TSMC, AMD and Amkor cover connectivity, custom chips, memory, GPUs, foundry and packaging; Broadcom expects AI revenue of about $115B in fiscal 2027. Vistra supplies power under 20-year nuclear contracts. IREN and Nebius rent AI compute, with Nebius targeting $7-9B run-rate revenue by year end. x.com  x.com  x.com  x.com  x.com  x.com  x.com  … Show more

Memory makers' pricing power looks unsustainable because betting on a long-term bottleneck is betting against human ingenuity. Memory players are squeezing customers in a way ASML and TSMC historically chose not to; Micron may have the right to get back at Apple, but that hurts long-term relationships, and disregarding the non-AI business could come back to bite. Even if inference demand drives memory prices, as @bnemethbrown argues, whether regular DRAM gets commoditized is still open. x.com  … Show more

Memory pooling and compute should lead the next rally because memory supply simply isn't there. Apple's reported lobbying to buy from CXMT is about missing supply, not price, since CXMT sells at only about a 5% discount, and Samsung and SK hynix plan two massive new fabs as a Korean national project, a sign countries treat the buildout as existential. Astera Labs, Credo, Penguin Solutions and Marvell are the memory pooling plays, and Credo offers good value after quarter-end rebalancing hit it. … Show more
