This paper describes a novel TCAM architecture designed for enhancing the soft-error immunity. An associated embedded DRAM and ECC circuits are placed next to TCAM macro to implement a unique methodology of recovering upset bits due to soft errors. The proposed configuration allows an improvement of soft-error immunity by 6 orders of magnitude compared with the conventional TCAM. We also propose a novel testing methodology of the soft-error rate with a fast parallel multi-bit test. In addition… CONTINUE READING
