  • CAM cell with interdigitated search and bit lines
    Patent number: 6760240
    Abstract: A method and structure for an array of content addressable memory (CAM) cells is disclosed. Each of the CAM cells has a search line and a bitline parallel to the search line. Across the array, search lines and bit lines of the CAM cells are interdigitated so that the search lines and bitlines alternate across the array. CAM cell macro's are inverted with respect to adjacent macros to balance parasitic capacitances across the array.
