  Citrini: AMD and Apple are both betting on flash memory to replace DRAM, potentially reducing memory costs by 55 times.
  面对DRAM暴涨，AI存储向低成本闪存转移。AMD收购MEXT将AI驱动闪存技术引入数据中心，苹果推进端侧闪存方案。巨头看重闪存成本仅为DRAM的1/55，正重构AI存储架构。

  The largest IPO in history! Musk: Hopes to advance SpaceX's IPO "soon"
  5月18日，马斯克表示，他希望“很快”推进SpaceX的首次公开募股（IPO）。此前消息，SpaceX正大幅加快IPO进程。原定于6月下旬（马斯克生日前后）的上市计划，现已调整为最早于下周三（5月20日）公开招股说明书，6月4日启动路演，6月11日确定发行价格，最早于6月12日正式挂牌交易，股票代码为“SPCX”。知情人士透露，美国证券交易委员会（SEC）对公司IPO文件的审查进度快于预期，是此次上市时间表提前的主要原因。

For this type of sequential data reading, the speed advantage of DRAM is significantly reduced, while the capacity advantage of flash memory is fully demonstrated.</p><p><p class=\"t-img-caption\"><img src=\"https://community-static.tradeup.com/news/8f9b061541f243d013842840b2a9af30\" data-align=\"center\" tg-width=\"1024\" tg-height=\"671\"/><span></span></p><p><p style=\"text-align: left;\">The expansion path of flash memory is also fundamentally different from that of DRAM. Flash memory increases capacity by vertically stacking more cell layers, relies on existing deposition and etching processes in existing factories, eliminates the need for new lithography nodes, and does not consume EUV resources. Flash memory controllers are manufactured based on proven 6/7 nanometer processes, away from the bottlenecks that are constraining advanced processes.</p><p><p style=\"text-align: left;\">A previous paper by Apple researchers, \"LLM in a Flash,\" provides methodological support: by storing large language model parameters in the device's Flash memory and retrieving them to DRAM on demand, models exceeding their capacity limit can be run on devices with limited DRAM capacity, and inference speeds can be achieved on the CPU and GPU, respectively, 4 to 5 times faster and 20 to 25 times faster than the simple loading method.</p><p><p class=\"t-img-caption\"><img src=\"https://community-static.tradeup.com/news/1b87a29aa7ba0ff023c247b4f54e9951\" data-align=\"center\" tg-width=\"1024\" tg-height=\"630\"/><span></span></p><p><h2 style=\"text-align: left;\">Two paths: Synchronous evolution between the data center and the edge</h2><p style=\"text-align: left;\">AMD's acquisition focuses on the data center scenario. By integrating MEXT technology into AMD's data center portfolio, AMD seeks to help enterprise customers improve resource efficiency and reduce costs in AI workload deployments. Morgan Stanley's Shawn Kim team believes that despite persistent memory shortages, AMD still has a structural advantage in the cloud market competition—\"Agent-driven AI-driven CPU demand is structurally beneficial for AMD's expansion of its cloud market share.\" Citi's optimistic forecast for AMD is more based on its GPU sales and...<a href=\"https://laohu8.com/S/NVDA\">NVIDIA</a>A positive competitive landscape.</p><p><p style=\"text-align: left;\">Apple's path, on the other hand, falls on the device side. The \"LLM in a Flash\" solution transfers the reliance of model inference on expensive cloud memory to the device's local Flash memory, reducing cloud computing costs while providing viable memory architecture support for edge AI applications.</p><p><p style=\"text-align: left;\">According to Citrini Research, both paths lead to the same conclusion:<strong>The memory layer of AI inference is being restructured. Low-frequency KV cache, model weights, and edge data will gradually sink from the expensive HBM/DRAM layer to the NAND Flash/SSD layer, forming a multi-tiered storage architecture.</strong></p><p><p style=\"text-align: left;\">This structural shift is creating a multi-layered transmission effect along the industrial chain. According to Citrini Research, the most direct beneficiaries are NAND manufacturers, with high-capacity NAND, enterprise-grade SSDs, and QLC NAND being the purest directions, including SanDisk,<a href=\"https://laohu8.com/S/WDC\">Western Data</a>Micron and Kioxia.</p><p><p style=\"text-align: left;\">The SSD controller layer is considered the most durable—the core of truly bringing flash memory closer to the memory experience lies in controller, firmware, and NVMe architecture optimization, involving...<a href=\"https://laohu8.com/S/SIMO\">Silicon Motion</a>, Marvell et al.
