Abstract

In digital systems design, strict reliability constraintsusually impose very low fault latency and high degree offault detection of permanent and transient faults. Inparticular, memory modules, as either devices or IP cores,appeared as one of the most critical parts. This paperpresents an advanced on-line memory BIST architectureimplemented as an IP core developed fortelecommunication applications at Italtel SpA, the majorItalian manufacturers of telecom systems. A fault latencyreduction architecture, a code-based fault detectionscheme, and an architecture-based fault avoidance havebeen composed to meet the required reliability constraints.
