Methods and Apparatus Providing High-Speed Content Addressable Memory (CAM) Search-Invalidates |
摘要 |
Embodiments of a Content Addressable Memory (CAM) enabling high-speed search and invalidate operations and methods of operation thereof are disclosed. In one embodiment, the CAM includes a CAM cell array including a number of CAM cells and a valid bit cell configured to generate a match indicator, and blocking circuitry configured to block an output of the valid bit cell from altering the match indicator during an invalidate process of a search and invalidate operation. Preferably, the output of the valid bit cell is blocked from affecting the match indicator for the CAM cell array beginning at a start of the invalidate process and continuing until an end of the search and invalidate operation.
