Abstract
A technique to enhance performance and reduce silicon area for a TCAM system which includes a plurality of CAM blocks that are organized into at least one rectangular array having rows each having a plurality of CAM blocks, a group of TCAM cells and associated read/write bit lines connecting the group of CAM cells to search bit lines. Each TCAM cell in the TCAM architecture includes a pair of memory elements that is connected to a pair of associated compare circuits such that the interconnections between the memory elements and the compare circuits are substantially vertical in active MOS layers and substantially horizontal in the metal layers to facilitate sharing of adjacent cells thereby providing reduced silicon area and a short aspect ratio.
