An apparatus for processing cache requests in a computing system is disclosed. The apparatus may include a single-port memory, a dual-port memory, and a control circuit. The single-port memory may be store tag information associated with a cache memory, and the dual-port memory may be configured to store state information associated with the cache memory. The control circuit may be configured to receive a request which includes a tag address, access the tag and state information stored in the single-port memory and the dual-port memory, respectively, dependent upon the received tag address. A determination of if the data associated with the received tag address is contained in the cache memory may be made the control circuit, and the control circuit may update and store state information in the dual-port memory responsive to the determination.
