Ph.D. Dissertation Defense by Sihang Liu

As the benefits from Moore’s Law are approaching an end, new technologies are being proposed and developed to satisfy the ever-growing demand for performance. One of these technologies is persistent memory, such as Intel’s recently released Optane DC Persistent Memory. It is a unification of memory and storage, satisfying the demand for better performance and higher memory capacity. However, the adaption of this new memory technology would require a redesign of the system stack, where both software and hardware aspects are critical to the adaption of persistent memory. In my dissertation research, I focus on both the software and hardware aspects of system support for persistent memory. On the software side, I ensure the correctness of software systems designed for this new memory technology. On the hardware side, I design efficient and secured persistent memory hardware systems.
