Re: What is the major problem faced in DFT with tri-state bu

Tri-state buffers are generally used for bidirectional IO's or to drive sharing buses . Chip Select (CS) of memories is an example. Tri-state buffer can be represented as : bufif0(PAD , I ,OEN) , bufif1(PAD , I ,OEN) . Issues with tri-state buffer :- 1. Probability of contention :- Bus contention oc...

Re: What are repairable memories

Repairable memories are memories with spare row/cloumn , which can be used as replacement of faulty row/column . So , with Repairable memories you can increase % yield.
