An efficient approach for memory repair by reducing the number of spares

In this paper, we proposed an approach to reduce the hardware required by the conventional algorithm CRESTA (Comprehensive Real-time Exhaustive Search Test and Analysis) by trying to share the hardware between different sub-analyzers. Experiments with synthesis for the case of three spare rows and three spare columns evidenced for saving at least 15% of hardware, and for the case of two spare rows and two spare columns - about 7%.
