The memory system will be a growing bottleneck for many workloads running on high-end servers. Performance improvements from technology scaling are also expected to decline in the coming decade. Therefore, new capabilities will be required in memory devices and memory controllers to achieve the next big leaps in performance and energy efficiency. Some of these capabilities will be inspired by emerging workloads (e.g., in-memory big-data, approximate computing, co-scheduled VMs), some will be inspired by new memory technologies (e.g., 3D stacking). The talk will discuss multiple early-stage projects in the Utah Arch lab that focus on DRAM parameter variation, near-data processing, and memory security.
