An Efficient March-Based Three-Phase Fault Location and Full Diagnosis Algorithm for Realistic Two-Operation Dynamic Faults in Random Access Memories

An Efficient March-Based Three-Phase Fault Location and Full Diagnosis Algorithm for Realistic Two-Operation Dynamic Faults in Random Access Memories

Previously, a minimal algorithm of length 70 N, N is the number of memory bits, was proposed for a subclass of dynamic faults. In this paper, a March-based fault location and full diagnosis algorithm of complexity 88 N+29 is proposed for the same subclass of dynamic faults in bit-oriented SRAMs.

Zusammenfassung:Previously, a minimal algorithm of length 70 N, N is the number of memory bits, was proposed for a subclass of dynamic faults. In this paper, a March-based fault location and full diagnosis algorithm of complexity 88 N+29 is proposed for the same subclass of dynamic faults in bit-oriented SRAMs.
