随着服务器和工作站中SRAM缓存和DRAM内存的增长，宇宙射线误差正成为系统设计人员和最终用户关注的主要问题。有几种技术可以检测和减轻宇宙射线扰动的发生，如错误检测、错误纠正、缓存清理和阵列交错。本文讨论了这些技术在面积、功率和性能损失与提高可靠性方面的权衡。在大多数系统应用程序中，需要几种技术的组合来满足必要的可靠性和数据完整性目标。
As the size of the SRAM cache and DRAM memory grows in servers and workstations, cosmic-ray errors are becoming a major concern for systems designers and end users. Several techniques exist to detect and mitigate the occurrence of cosmic-ray upset, such as error detection, error correction, cache scrubbing, and array interleaving. This paper covers the tradeoffs of these techniques in terms of area, power, and performance penalties versus increased reliability. In most system applications, a combination of several techniques is required to meet the necessary reliability and data-integrity targets.
