加州大学河滨分校研究：将 HBM4 控制器功能迁移到更靠近内存的位置

Shifting HBM4 Controller Functions Closer To Memory (UC Riverside)

AI 导读

加州大学河滨分校的 Tharunya Yogananda 和 Wantong Li 发表论文，提出首个针对 HBM4 控制器功能在主机与 HBM 基底裸片之间划分的系统性定量研究。由于 HBM4 的基底裸片可采用逻辑工艺制造，更复杂的控制器功能可置于 DRAM 旁；研究将控制器按功能拆分，评估了从完全主机控制器到完全基底裸片控制器的四种放置方案。

Tharunya Yogananda and Wantong Li of the University of California, Riverside published a technical paper titled “Beyond Host-Side Control: HBM Controller Partitioning Across Host and HBM Base Dies.”

Abstract Excerpt:

“Recent generations of high bandwidth memory (HBM), such as HBM4, allow the base die of the memory stack to be manufactured using a logic process that can accommodate more complex controller functions next to the DRAM. We present the first systematic quantitative study of function-level controller placement between the host and the HBM4 base die on a silicon interposer. We divide the controller into its main functions and evaluate four placements, from a complete host controller to a complete base die controller, with intermediate placements that move maintenance or scheduling to the base die. “
