Description
The analysis of linked faults (LFs), which are faults that influence the behavior of each other, such that masking can occur, has proven to be a source for new memory tests, characterized by an increased fault coverage. However, many newly reported fault models have not been investigated from the point-of-view of LFs. This paper presents a complete analysis of LFs, based on the concept of fault primitives, such that the whole space of LFs is investigated and accounted for and validated. Some simulated defective circuits, showing linked-fault behavior, will be also presented. The paper establishes detection conditions along with new tests to detect each fault class. The tests are merged into a single test March SL detecting all considered LFs. Preliminary test results, based on Intel advanced caches, show that its fault coverage is high as compared with all other traditional tests and that it detects some unique faults …
