Original Abstract Submitted
The present disclosure discloses a content addressable memory apparatus. A self-test control circuit generates self-test driving signals and control an external test pattern generation circuit generates search data and an address signal. A content addressable memory circuit includes a memory circuit, an internal test pattern generation circuit and an internal comparison circuit. The memory circuit receives the search data and the address signal from the external test pattern generation circuit to perform search operation to generate actual match signals corresponding to the match lines. The internal test pattern generation circuit receives the self-test driving signals from the self-test control circuit to generate expected match signals. The internal comparison circuit receives and compares the actual match signals and the expected match signals to generate match comparison results such that the self-test control circuit receives the match comparison results and performs verification accordingly.
