CONTENT ADDRESSABLE MEMORY

摘要

A content addressable memory (CAM) is disclosed. The CAM has first and second CAM cells (710, 720, 730, 740) in which each adjacent CAM cell is rotated 180 relative to its neighbor, which provides a compact physical arrangement having overall matched CAM array cell and RAM array cell row heights. Further, an interleaved set scheme can be applied to the CAM cells to provide reduced routing of compare signals and reduced parasitic capacitance. The first and second CAM cells may be vertically stacked.
