<p>PROBLEM TO BE SOLVED: To provide a CAM(content addressable memory) retrieval system for suppressing occurrence of plural coincidence caused by erroneous CAM data region and other address hit. SOLUTION: When stored information 104 is given from a control system, a CAM control section 2 adds parity to it and stores it in a CAM 1. When retrieving information 101 is given from the control system, the CAM control section 2 performs retrieving for the CAM 1 by a CAM retrieving information 102 in which parity is added to the above, and monitors normality of the CAM 1 by a retrieved result 103 of the CAM 1.</p> |
