Abstract: The world’s insatiable demand for computing is having a global impact. I will discuss two outstanding challenges in computing: the memory wall or communication wall, and computing’s carbon footprint. My approach to overcome these challenges leverages three-dimensional integrated circuits (3D ICs). I will present a 3D embedded DRAM to address the memory wall, and show how we model the carbon footprint of 3D ICs. I will also discuss 3D Electronic-Photonic ICs to address the communication wall.
