Abstract

A memory apparatus for detecting false hits in a content-addressable memory (CAM) is disclosed. The memory apparatus includes a controller coupled to the CAM and a memory. The controller receives a search result including an address from the CAM, the address corresponding to a matching entry from a first set of data entries that matches a search tag. The controller provides a read address based on the address to the memory, which returns a second data entry from a second set of data entries corresponding to the read address. The controller receives the read data and generates an error detection result based on a comparison between the second data entry and the search tag.
