Abstract
A search engine system () is disclosed that can include at least one content addressable memory (CAM) device () arranged in a cascade configuration with at least one memory device (), such as a static random access memory (SRAM). A CAM device () and memory device () may be connected to one another by point-to-point unidirectional connections. Command data issued by a device, such as a network processing unit (NPU) (), can flow through all devices beginning with a CAM device () and eventually to a memory device (). A memory device () can compare its own current result data with that of a previous device in a flow (such as another RAM device), and generate an output response.
