CAM is used for high-speed search operations. When searching for data
within a RAM block, the search is performed serially. Thus, finding a
particular data word can take many cycles. CAM searches all addresses in
parallel and outputs the address storing a particular word. When a match
is found, a match flag is set high. Figure 23 shows the CAM block
diagram.
