英特尔正寻求以全新内存架ĉ00;挑战高带宽内存(HBM)的主导地位,但商业化前景仍遥遥无期。
英特尔近期公布的专利申请揭示了其“跨批次内存”(XBM)架构方案。该设计旨在绕开现有HBM对硅中介层(interposer)的依赖,通过后端工艺晶体管与串行UCIe互连取代传统DRAM及其超宽接口,从而大幅压缩封装成本。
据行业报道,XBM的商业化目标时间节点定在2030年之后,与英特尔联合软银旗下SAIMEMORY共同开发的ZAM内存架构时间线一致。 当前HBM市场由韩国厂商主导,供应紧张与成本高企推动业界探索替代方案,英特尔专利为竞争格局增添新变量,但生态系统壁垒与平台兼容性问题将成其市场化主要障碍。
XBM架构的核心在于将DRAM模块连接至运行速率32 GT/s的UCIe I/O模块,I/O信号通过基础芯片(base die)路由。每个XBM堆栈单芯片容量0.5GB至5GB;子通道由12个数据模块构成,8层堆栈最多容纳96个数据模块,16层可达192个,通道运行频率2GHz。封装形式支持多种配置,包括封装上内存(Memory-on-Package,MoP),可在更小外形尺寸内实现更高带宽与容量,此灵活性被视为其相较于现有HBMǚ..
