A process performed using a CAM when an error is not generated in the data stored in the CAM, can be continued even if an error is generated in the data stored in the CAM. An input character code is provided to a compressed data path and a non-compressed data path. In the compressed data path, a repeat data retrieval circuit (21) outputs a coincident address of a character string in the CAM and a character string coincident signal which indicates the coincidence of the character string in the CAM. On the other hand, in the non-compressed data path, flip-flops (1001 to 1004) send the character code without any changes. A selector (98) outputs the coincident address and the number of consecutive outputs of the character string coincident signals from the compressed data path if a parity error signal is not output from the repeat data retrieval circuit (21) and the number of consecutive outputs of the character string coincident signals is three or greater, and if not, outputs the character code from the non-compressed data path. |
