Core Viewpoint - The article highlights the significant advancements and innovations in the 3D NAND flash memory technology developed by Yangtze Memory Technologies Co., Ltd. (YMTC), particularly through its Xtacking® architecture, which has achieved notable industry recognition and awards for its innovative design and performance improvements [3][9][11]. Summary by Sections Xtacking® Architecture Development - In 2018, YMTC launched the Xtacking® architecture, which separates the storage array and peripheral circuits onto different wafers for parallel processing, enhancing manufacturing flexibility and device compatibility [6]. - The architecture has evolved through several versions, with Xtacking® 4.0 currently offering improved interface speeds, higher storage density, and enhanced reliability [11]. Technical Innovations - Xtacking® 2.0 introduced a dual-stacking architecture that reduced the difficulty of etching channel holes, improving signal transmission performance and overall system performance [7]. - Xtacking® 3.0 simplified the manufacturing process by converting complex 3D structures into 2D, leading to cost reductions and improved read/write performance [8]. Performance Metrics - The Xtacking® 4.0 design features a chip size of 40.44 square millimeters, achieving a density of 12.66 Gb/mm² for a 512 Gb chip, thus providing higher storage density within a smaller area [9]. Industry Recognition - The Xtacking® architecture has received multiple awards, including the "Best of Show" at the Flash Memory Summit in 2018 and the "Most Innovative Storage Technology Award" at the FMS 2022 and FMS 2025, recognizing its contributions to the field of 3D NAND technology [9][11].

如果您希望可以时常见面，欢迎标星收藏哦~ 今天下午，上市公司河北养元智汇饮品股份有限公司对外发布公告称，公司投资了长江存储 科技控股有限责任公司（以下简称"长控集团"或"标的公司"）。公告指出，本次投资金额为 人民币 16 亿元。本次交易完成后，公司控制的芜湖闻名泉泓投资管理合伙企业（有限合 伙）（以下简称"泉泓投资"）持有长控集团0.99%的股份。 据企查查消息透露，本次的被投标的是"长江存储科技控股有限责任公司"法人为陈南翔，旗下公 司包括长江存储科技有限责任公司、武汉新芯集成电路股份有限公司以及宏茂微等一系列子公 司。其中长江存储科技有限责任公司就是我们平时俗称的"长江存储"，也就是国内3D NAND的 唯一供应商。 至于本次被投标的是其母公司。换而言之，我们不能通过这个投资金额和在公司中的股份占比粗 暴计算"长江存储"的估值。而在引入了包括河北养元智汇饮品股份有限公司及一系列的新股东之 后，"长控集团"股东更多元化，为"长江存储"后续的发展打开了一个新局面。 官网资料显示，长江存储科技有限责任公司成立于2016年7月，总部位于"江城"武汉，是一家集 芯片设计、生产制造、封装测试及系统解决方案产品于一体 ...
