| 摘 要： | 针对三维集成电路的软错误问题，分析了高能粒子进入三维堆叠芯片中的运行轨迹和特性，在分析高速缓冲存储器（Cache）中各部分软错误易感性的基础上，提出了一种基于三维堆叠技术的高可靠性Cache结构R3D Cache，利用三维堆叠芯片的层间屏蔽效应，以较小的面积和性能开销大幅降低了其软错误率.结果表明，所提出的R3D Cache结构能够以0.52%~4.17%的面积开销，将Cache的软错误率降低到原来的5%，而所带来的性能开销可以忽略.

| Abstract: | Focused on soft error issue in 3D integrated circuits, this paper analyzed particles tracks and characters when high energy particles get into 3D stacking chips, and then presented a kind of 3D stacking technology based reliable Cache architecture R3D Cache after analyzing soft error vulnerability of each component of Caches. The R3D Cache can greatly reduce error rate with little area and performance overheads. The analysis results show that the proposed structure can bring down soft error rate of Caches to 5% of original one with 0.52% to 4.17% area overhead, while the performance overhead can be ignored. |
