ABSTRACT:
An error detection and correction circuit is connected to at least one memory bank of a CAM device. During background processing (i.e., when the CAM is not performing reading, writing or searching functions) the error detection and correction circuit tests all of the CAM locations that it is connected to in sequence. If an error is detected, the error detection and correction circuit rewrites the CAM location with the correct data. Multiple error correction and detection circuits can be used in the CAM device to test multiple CAM locations simultaneously.
