英文摘要	We propose an energy-efficient reconfigurable in-package graphics memory design that integrates wide-interface graphics DRAMs with GPU on a silicon interposer. We reduce the memory power consumption by scaling down the supply voltage and frequency while maintaining the same or higher peak bandwidth. Furthermore, we design a reconfigurable memory interface and propose two reconfiguration mechanisms to optimize system energy efficiency and throughput. The proposed memory architecture can reduce memory power consumption up to 54%, without reconfiguration. The reconfigurable interface can improve system energy efficiency by 23% and throughput by 30% under a power budget of 240W*. ? 2012 ACM.; EI; 0
