Fault detection with optimum March Test Algorithm
Integrating a large number of embedded memories in System-on-Chips (SoC’s) occupies up to more than 70% of the die size, thus requiring Built-In Self-Test (BIST) with the smallest possible area overhead. This paper analyzes MATS++(6N), March C-(10N), March SR(14N), and March CL(12N) test algori...

| Summary: | Integrating a large number of embedded memories in
System-on-Chips (SoC’s) occupies up to more than 70% of the
die size, thus requiring Built-In Self-Test (BIST) with the smallest
possible area overhead. This paper analyzes MATS++(6N),
March C-(10N), March SR(14N), and March CL(12N) test
algorithms and shows that they cannot detect either Write
Disturb Faults (WDFs) or Deceptive Read Destructive Faults
(DRDFs) or both. Therefore to improve fault detection, an
automation program is developed based on sequence operation
(SQ) generation rules. However after solving the undetected
fault, the outcome in term of its detection result of Static Double
Cell Faults using the specified test algorithm especially
Transition Coupling Faults (CFtrs), Write Destructive Coupling
Faults (CFwds), Read Destructive Coupling Faults (CFrds) and
Deceptive Read Destructive Faults (CFdrds) are observed. |
