This paper proposes a design of a defect tolerant Wallace multipliers. A repair procedure for the pro- posed design i s also shown. T h i s paper evaluates t h e proposed design from the view point of t h e yield, area and delay time. For example, the yield of a 32 x 32 Wallace multiplier increases from 0.90 t o 0.99 by applying the proposed design while the area increases by a factor of 1.39.
