摘要：
A high-reliability content & addressable memory using a shadow content-addressable memory (CAM) array in parallel with a primary CAM array to increase the reliability of CAM searches. The reliability of CAM searches has been less than desired because of random environmental influences that corrupt data. The shadow CAM is written, read, and searched in parallel with the primary CAM. The search results from the parallel searches are compared and, if identical, are declared valid. If the search results are not equal, corrective action is initiated. The high-reliability content-addressable memory may be used with or without priority encoders.
