This is a tour through recent and prominent works regarding new DRAM chip designs and technologies, near data processing approaches,
new memory channel architectures, techniques to tolerate the overheads of refresh and fault tolerance, security attacks and
mitigations, and memory scheduling.The memory system will soon be a hub for future innovation. While conventional memory systems
focused primarily on high density, other memory system metrics like energy, security, and reliability are grabbing modern
research headlines. With processor performance stagnating, it is also time to consider new programming models that move some
application computations into the memory system. This, in turn, will lead to feature-rich memory systems with new interfaces.
The past decade has seen a number of memory system innovations that point to this future where the memory system will be much
more than dense rows of unintelligent bits.
