Abstract
An improved structure and method of operation are provided wherein a single RAM (random access memory) can be serviced by two CAMs (content addressable memory). This is accomplished by providing first actuating circuitry operably associated with and operatively connecting a first CAM to a selected portion of the RAM and second actuating circuit associated with and operably connecting a second CAM to a second portion of the RAM. The first actuating circuitry includes circuitry to actuate a selected wordline responsive to a CAM search read and RAM search read and circuitry to initiate a CAMRAM index read and index write operably responsive to given control logic. The second circuitry includes circuitry to actuate a selected wordline responsive to a CAM search read and RAM search read responsive to given control logic.
