Programmable Test Pattern Generator And Controller, Sandeep Bhatia

Defensive Publications Series

Memories are typically tested using preset test patterns that exercise the memory core. In the case of embedded memories, e.g., where memory is integrated within an application-specific integrated circuit (ASIC), conventional testing is not effective in uncovering defects in the memory-ASIC interface. Stress conditions, e.g., excessive bus activity, saturated interface bandwidth, power surges, noise, etc., that arise in operation are not reproduced adequately in the test phase. Memory defects that manifest under specific conditions, e.g., after many cycles of memory access, under certain data/address sequences, when neighboring memory cells hold particular values, etc., are often not uncovered.
