$Roundhill Memory ETF(DRAM)$  CXMT as competition to Micron is honestly a fraud. They are stuck at 1x/1y/early‑1z DRAM nodes, and their most advanced DRAM is still built on legacy multi‑patterned DUV, which limits them to roughly 18–20 nm class for 1x, around 16–17 nm class for 1y, and about 15–16 nm class for early 1z. Those nodes are 5–7 years behind Micron's leading nodes. CXMT cannot shrink DRAM cells further because DRAM capacitor and bitline geometry hits a hard wall without EUV. They cannot produce 1α DRAM, 1β DRAM, 1γ DRAM, or HBM2E / HBM3 / HBM3E. They are permanently stuck in DDR4‑era physics with cheap inferior chips. Their DDR5 is fake — it is DDR4‑class DRAM with DDR5 branding, missing real DDR5 speeds, timing architecture, ODECC, density, reliability, and qualification. Micron's DDR5 is world‑class, built on 1α/1β nodes, and used in servers, PCs, and AI systems. Micron produces the full, real DDR5 portfolio — from PC UDIMMs to server RDIMMs to ultra‑dense 24Gb dies — and they are considered the highest‑quality DDR5 in the industry. CXMT's DDR5 is not competitive and is treated as low‑end DRAM for cost‑down China‑only products or junk. And the gap will only widen as China is prohibited from buying advanced fab machines. If you ever buy a Chinese computer or product with CXMT DRAM, you have bought junk.
