WebThe memory BIST engine selected by the SoC designer needs to solve these challenges via combination of hard and soft repair capabilities, an extended class of test algorithms, and the inclusion of a programmable sequence of steps to perform calibration/trimming. Webmemory normal operation mode, and repair the hard faults during the memory idle time as long as there are unused redundant elements. We also develop a method for evaluating the memory reliability. Experimental results show that the proposed approach is effective, e.g., the MTTF of an 32N× 64 our integrated ECC and repair scheme. 1 Introduction
