Abstract:
A ternary content addressable memory (TCAM) device includes a memory cell. The memory cell includes a data storage circuit, a limiter circuit, and a discharge circuit. The data storage circuit includes a first resistor and a second resistor connected in series to divide a voltage corresponding to search data, and configured to store cell data. The limiter circuit is configured to receive the divided voltage through an input terminal and transmit an output voltage through an output terminal based on a level of the divided voltage. The discharge circuit discharges a matching line indicating whether the stored cell data matches with the search data, based on the output voltage of the limiter circuit.
