Method and apparatus of local word-line redundancy in CAM |
摘要 |
A local word-line redundancy architecture and method that implements both word-line and match-line steering for semiconductor memories and more particularly for content-addressable memories (CAM) are introduced. According to the present invention, the method of performing local word-line redundancy comprising: testing by using BIST, storing results, comparing failing read address data and failing match-line address data to determine if redundancy is possible and, if so, storing the redundancy repair data pattern and loading that patten upon initialization so that redundancy steering is activated.
