ABSTRACT:
A signal detection circuit detects the presence or absence of signals having the same logic in a plurality of arranged signal lines, can be used as a circuit suitable for multi-hit detection in a content addressable memory. The signal detection circuit includes a first signal transmission line to transmit a first signal indicating the presence of two or more logical signals to be detected and a second signal transmission line to transmit a second signal indicating the presence of one or more of the logic signals to be detected. Each of the first and second signal transmission lines includes logic circuits. The signal detection circuit may have a hierarchical structure.
