Abstract
A method for content addressable memory (CAM) error recovery that includes detecting an error in an entry of a CAM, identifying an address of the entry in the CAM, copying data from the address in the backup random access memory (RAM) into the entry of the CAM to obtain a corrected CAM, clearing a results (first in first out) FIFO structure based on detecting the error, performing, using the corrected CAM, a match request stored in a replay FIFO structure to obtain a revised result, and storing the revised result in the results FIFO structure.
