Abstract(in English) | In this study we evaluate the effectiveness of hardware overhead reduction of memory BIST and spare assignment algorithm. For a given memory cell fail rate, we theoretically analyze the area per a good die of an SoC with multiple SRAMs. We then propose the heuristic algorithm which determine whether each SRAM has the redundant row or not so that the area per a good die is minimized. We further propose the encoder-based comparator with small hardware overhead. With the memory benchmark SoCs which have more than 1000 SRAMs, the proposed comparator with heuristic algorithm is evaluated under several scenarios. The result shows that the overhead of encoder-based comparator is about the half of the conventional one, and combined with the heuristic algorithm it can reduce the total SoC area per a good die by 0.7%. |
