Combining switch and site yields for soft-configurable WSI

The configuration requirements of a soft-configurable pipelined memory are described. Monte Carlo simulations show that wafer yield dependence on high switch yields can be reduced substantially using switch path bypasses and/or spare columns. These simulations combine the effects of switch and site failures in ways that cannot easily be captured using simpler analytic models, due to interdependencies between the effects of switch and site failures on system configuration.<
