If each repairable RAM uses one self contained BISR circuit (Dedicated BISR scheme), then the area cost of BISR circuits in an SOC becomes high. This, results in converse effect in the yield of RAMs.

This paper presents a test scheduling approach for BISR memory cores under the constraint of maximum power consumption. An efficient test scheduling algorithm based on the early-abort probability is proposed.
