ABSTRACT:
A method of placing a content addressable memory (CAM) into a low current state is disclosed. The CAM can include at least one storage location that does not store valid data for a compare operation and includes a plurality of CAM cells, each CAM cell having at least two data controllable impedance paths arranged in parallel with one another. The method can include configuring the majority of the CAM cells to store data values that maintain the corresponding at least two data controllable impedance paths in high impedance states.
