MI455 芯片在 CoWoS-L 封装中首次亮相主动互连桥接器

据报道,MI455 芯片是首款在其 CoWoS-L 封装中集成主动式本地硅互连 (LSI) 桥接器的芯片。与之前的被动桥接器不同,这些主动式 LSI 包含再生信号的电路,可能允许更小的 PHY 以及更多的计算和内存硅。这项由台积电展示的进步似乎是一个已上市的产品,而不是一个研究载体,它包含两个基板芯片、十二个 HBM4 堆栈和两个 IO 芯片。 AI

影响 能够更有效地集成 chiplet,可能带来更强大、更专业的 AI 硬件。

    我们相信MI455是首款出货时带有主动式本地硅互连(LSI)桥接器的芯片,这是CoWoS-L封装内的chiplet到chiplet连接

    We believe the MI455 is the first known chip to ship with active Local Silicon Interconnect (LSI) bridges, the chiplet-to-chiplet links inside a CoWoS-L package. In CoWoS-L's short history, those bridges have always been passive: wiring and capacitors, nothing more. Active LSIs …
