Abstract
Systems and methods disclosed herein provide for improved diagnostics for memory built-in self-test ('MBIST'). Embodiments provide for a two-pass diagnostic test of the target memory, wherein, in the first pass, a data compare unit provides clock cycle values associated with detected mis-compares to a tester, and, in the second pass, the data compare unit extracts data vectors associated with the clock cycle values. Embodiments further provide for a bit fail map report that is generated based on the extracted data vectors.
