Advanced ECC Solution for Automotive SoCs

摘要

The modern automotive industry has entered an era where the tendencies are towards increased automation and connectivity. With every new generation, the proportion of electronics-controlled systems in the vehicles is steadily growing. In parallel the safety and reliability requirements to automobiles are becoming more stringent thus requiring more sophisticated approaches. The problem is complicated by the fact that automotive has started to use cutting-edge technologies whose maturity might not be always at high level. Thus, there is a need to ensure not only low DPPM during production mode but also high reliability during mission mode. This paper presents an advanced Error Correcting Codes (ECC) solution which ensures high level of single-bit and multi-bit error detection and correction for memories operating in mission mode. This solution addresses the main requirements posed by automotive industry as well as successfully passed ISO 26262 certification with ASIL-D grade.
