摘要

In this paper, we discuss reliability of a computer system which consists of various IC components. We focus on the difference between SERs of SRAM and DRAM memories and analyze a tradeoff between reliability and performance of a computer system. We also propose reliable cache architectures for both reliability and performance. We introduce reliability and performance modes for reliable cache architectures. Controlling the operation mode of a computer system decreases vulnerability of a computer system under a certain performance constraint. Our experiments show that switching the operation modes of the cache memories affects performance and reliability of a computer system and is effective for tuning its performance and reliability.
