Abstract

Using a cache vulnerability factor to measure the susceptibility of cache memories to transient errors at the architecture level can help designers make appropriate cost and reliability trade-offs at early design cycles. Two early write-back strategies can also improve the reliability of write-back data caches without compromising performance.
