It becomes increasingly difficult to achieve a high manufacturing yield for multi-core chips due to larger chip sizes, higher device densities, and greater failure rates. By adding a limited number of spare cores to replace defective cores either before shipment or in the field, the effective yield of the chip and its overall cost can be significantly improved. In this paper, we propose a yield and cost analysis framework to better understand the dependency of a multi-core chip's cost on key… CONTINUE READING
