Abstract
A three-port content addressable memory (CAM) device and method thereof are provided. The three-port CAM device includes a CAM, a search control block, and a maintenance control block. The CAM is configured to store data. The search control block is arranged to receive search data and search control signals via a first port for searching the search data in the CAM. The search control block is further configured to perform search operations by accessing the CAM. The search operations are performed within search cycles with each search operation being performed over multiple clock cycles. In this configuration, more than one search operations are capable of being performed simultaneously over one or more clock cycles. Search results of the search operations are output via a second port. The maintenance control block is configured to perform read/write operations by reading or writing specified data in the CAM via a third port.
