Abstract
A self diagnosis (BISD) device for a random memory array, preferably integrated with the random access memory, executes a certain number of predefined test algorithms and identifies addresses of faulty locations. The BISD device recognizes certain fail patterns of interest and generates bit-strings corresponding to them. In practice, the BISD device may diagnose memory arrays and allow the identification of defects in the production process that affect a new technology during its learning phase, thus accelerating its maturation.
