        The memory system is a fundamental performance and energy
        bottleneck in almost all computing systems. Recent system
        design, application, and technology trends that require more
        capacity, bandwidth, efficiency, and predictability out of the
        memory system make it an even more important system
        bottleneck. At the same time, DRAM and flash technologies are
        experiencing difficult technology scaling challenges that make
        the maintenance and enhancement of their capacity,
        energy-efficiency, and reliability significantly more costly
        with conventional techniques.

       In this talk, we examine some promising research and design
       directions to overcome challenges posed by memory
       scaling. Specifically, we discuss three key solution
       directions: 1) enabling new memory architectures, functions,
       interfaces, and better integration of the memory and the rest
       of the system, 2) designing a memory system that intelligently
       employs multiple memory technologies and coordinates memory
       and storage management using non-volatile memory technologies,
       3) providing predictable performance and QoS to applications
       sharing the memory/storage system. If time permits, we might
       also briefly touch upon our ongoing related work in combating
       scaling challenges of NAND flash memory.
