[Seminar] Memory Organizations for 3D Die Stacking
Contact : Prof. Jaejin Lee (02-880-1863)
This talk provides a brief overview of die-stacking technologies, covering some of the different options out there for stacking. I will then focus on architectural approaches for 3D-stacked memories, as this is one of the first major application areas of die stacking. For markets that require significant memory capacity and upgradable memory, die-stacked DRAM alone will not be sufficient, which creates technical challenges for the architecture and overall system organization. This talk will focus on techniques to integrate the stacked memory in a software-transparent fashion, but we will also discuss challenges and open research directions for exposing the heterogeneity of this kind of memory system to the software stack.
