TLDR

China’s CXMT said its fifth-generation DRAM platform had entered mass production, Reuters reports. The agency describes the claimed breakthrough as a step that could help China build a stronger competitor to Samsung, SK Hynix and Micron in memory chips. Caixin reports that CXMT also claims increased chip output and improvements in storage density, power consumption and cost control.

StatementDog | AI & Tech Supply Chains@statementdogCXMT says its fifth-generation DRAM platform is now in mass production, along with two 24Gb LPDDR5X products built on it. The company says the platform has an 11.95nm half-pitch in the memory array’s active area, uses quadruple patterning, and has capacitors with a 45-to-1 aspect ratio. Analysts who initiated coverage of CXMT in late August had that generation, which they pegged at roughly 15nm class, going into mass production in H2 2028. They also had CXMT about two generations behind Samsung and Micron, with restricted EUV access as the main brake. Node class and array half-pitch are measured differently, so the 11.95nm figure does not directly map to the analysts’ 15nm classification. Their supply model counts about 300,000 wafers a month in 2026 and roughly 100,000 more each year after that. CXMT says the new platform gets more than 50% more gross die out of the same wafer at an 8Gb basis, its own figure, which would lift bit output without adding wafer starts. https://www.reuters.com/world/asia-pacific/chinas-cxmt-says-new-memory-chip-platform-enters-mass-production-2026-09-20/20d
💻🎒@CodingNoobieDAILY TECH NEWS ROUNDUP 🚨 Everything important that happened in tech during the last 24 hours: • CXMT has entered mass production of fifth-generation DRAM and launched 24Gb LPDDR5X chips, challenging Samsung, SK Hynix and Micron. • The U.S. and China opened talks on AI models, tariffs and critical minerals ahead of the Trump-Xi summit. • ASML has begun operations in India as the country expands its semiconductor ecosystem and Tata Electronics’ chip ambitions. • Alibaba’s Qwen team open-sourced Qwen-Image-2.1, a 7B image generation and editing model with support across major open-source AI tools. • Researchers found two Codex sandbox escapes that could let malicious code execute commands on a developer’s host, and OpenAI has patched them. • Google said Gemini breached three real companies during a security test, highlighting risks from autonomous AI agents interacting with live systems.20d
Aｍatsu77@amatsuda7中国、先端メモリチップで大きな飛躍 中国のメモリチップメーカーであるCXMT（長鑫存儲）が、第5世代DRAMプラットフォームの量産を開始したと『環球時報（Global Times）』が報じました。 ◼️ 「G5」プラットフォームは、高度な「クアッドパターニング（4重露光）」技術を採用し、メモリセルアレイ のピッチを11.95nmまで微細化しています。 ◼️ この新プロセスにより、ウェハー1枚あたりのダイ（チップ）数が、第4世代プラットフォームと比較して少なくとも50%増加しました。 ◼️ G5プラットフォームは、中・ハイエンドのスマートフォンや携帯型民生用電子機器向けに設計されています。 ◼️ 同社によると、この新技術はエネルギー効率の向上やコスト管理の改善も実現しています。 今回の技術的進歩は、AIインフラ需要の急増に伴い世界のメモリ消費量が増大する一方で、中国が半導体の自給自足体制の強化とサプライチェーンの強靭化を推進している中で達成されました。 Sputnik20d

Unveiled 24Gb LPDDR5X parts are already in mass production; claims ~12nm feature spacing via quadruple patterning and ≥50% more dies per wafer vs the 4th-gen platform.
