ABSTRACT:
Segmented CAM arrays are provided with dual-capture match line signal repeaters that support high speed pipelined search operations. A dual-capture match line signal repeater may extend between xR and xS segments of CAM cells within a respective row. This repeater provides high speed operation by quickly accessing the state (match or miss) of a match line segment when a corresponding segment of CAM cells connected to the match line segment undergo a respective stage of a pipelined search operation. If the match line segment is initially assessed as having a match signal thereon, then that match signal is passed to a next higher match line segment within the same row and a next stage search operation is commenced. However, if the match line segment is erroneously assessed as having a match signal thereon, when a miss condition was actually present in the corresponding segment of CAM cells, then the signal repeater will operate to capture a late miss signal and pass that late miss signal to the next higher match line segment to correct an error.
