Optical chip-to-chip interconnects for memory systems

This study explores multi-drop interconnections over point to point interconnections. However, high data rate point-to-point electrical transmission lines make multi-drop interconnections very difficult to implement at high speeds. For high speed multi-drop processor to memory interconnections, this paper proposes that optical interconnections offer a simple procedure to design and implement alternative to point to point electrical interconnections. The design complexity of these optical interconnections is similar to lower speed multi-drop electrical interconnections that are currently the dominant architectural implementation in current computing systems.
