    Abstract: The rigid interface of current DRAM chips places the
    memory controller completely in charge of DRAM control. Even DRAM
    maintenance operations, which are used to ensure correct
    operation (e.g., refresh) and combat reliability/security issues
    of DRAM (e.g., RowHammer), are managed by the memory controller.
    Thus, implementing new maintenance operations or modifying the
    existing ones often require difficult-to-realize changes in the
    DRAM interface, memory controller, and potentially other system
    components (e.g., system software), leading to slow progress in
    DRAM-based systems.
    In this paper, our goal is to 1) ease the process of enabling new
    DRAM maintenance operations and 2) enable more efficient in-DRAM
    maintenance operations. Our idea is to set the memory controller
    free from managing DRAM maintenance. To this end, we propose
    Self-Managing DRAM (SMD), a new low-cost DRAM architecture that
    enables implementing new in-DRAM maintenance mechanisms (or
    modifying old ones) with no further changes in the DRAM
    interface, memory controller, or other system components. We use
    SMD to implement new in-DRAM maintenance mechanisms for three use
    cases: 1) periodic refresh, 2) RowHammer protection, and 3)
    memory scrubbing. Our evaluations show that SMD-based maintenance
    operations significantly improve the system performance and
    energy efficiency while providing higher reliability compared to
    conventional DDR4 DRAM. A combination of SMD-based maintenance
    mechanisms that perform refresh, RowHammer protection, and memory
    scrubbing achieve 7.6% speedup and consume 5.2% less DRAM energy
    on average across 20 memory-intensive four-core workloads.
