Abstract Bitmapping based on memory built-in self-test is the most efficient method to locate embedded memory defects in system-on-chips. Although this is the preferred approach to memory yield improvement, the procedure to enable bitmapping can be both time and resource-consuming. Therefore, it is not supported on chips that are not produced in high volume due to the low return on investment. EeLADA was explored as an alternative. Although its feasibility has been proven in a previous report, the localization capability or diagnostic resolution is limited to at best failing bit-lines. This work enhances this technique to achieve a resolution down to bit-cell level with an accuracy of less than 5 µm.
