On the effectiveness of hybrid mechanisms on reduction of parametric failures in caches

Abstract

In this paper, we provide an insight on the different proactive read/write assist methods (wordline boosting & adaptive body biasing) that help in preventing (and reducing) parametric failures when coupled with reactive techniques like ECC and redundancy which cope with already existent failures. While proactive and reactive have been previously viewed as complementary techniques, we show that it is not necessarily the case when considering the benefits of such hybrid schemes.
