Abstract
A content addressable memory (CAM) device can include a plurality of CAM cells each formed within a cell area of a substrate. Each cell area can have a cell length dimension in a first direction parallel to a substrate surface. The CAM device can also include at least one common line comprising a contiguous region of the substrate doped to a first conductivity type and formed in a base semiconductor region doped to a second conductivity type. The common line can extend in the first direction for more than one cell length and can be commonly coupled to non-power supply connections to the plurality of CAM cells.
