Technology scaling has resulted in a
steady increase in transistor speed. However, unlike
transistors, global wires that span across the chip show a
reverse trend of getting slower with shrinking process.
Modern processors are severely constrained by wire delay and
the widening gap between transistors and wires will only
exacerbate the problem. Following the traditional design
approach of adopting a single design point for all global
wires will be suboptimal in terms of both power and
...

As conventional memory technologies such as DRAM and Flash run into scaling challenges, architects and system designers are forced to look at alternative technologies for building future computer systems. This synthesis lecture begins by listing the requirements for a next generation memory technology and briefly surveys the landscape of novel non-volatile memories. Among these, Phase Change Memory (PCM) is emerging as a leading contender, and the authors discuss the material, device, and circuit advances underlying this exciting technology. The lecture then describes architectural solutions...
