UC Riverside Studies How HBM4 Controller Functions Are Split Between Host and Base Die
Understand the story
Researchers Tharunya Yogananda and Wantong Li of UC Riverside published a paper presenting the first systematic quantitative study of how HBM4 controller functions can be partitioned between the host and the HBM base die. Since the HBM4 base die can be fabricated with a logic process, more complex controller functions can be placed next to the DRAM. The study breaks the controller down by function and evaluates four placement schemes ranging from a fully host-based controller to a fully base-die-based controller. The work has so far been released as a paper, with no reported follow-up deployment progress.
