Abstract

A content-addressable memory (CAM) has a memory array for storing data, the memory array having E entries each having N data bits and a valid bit. The functionality of the CAM is tested by testing the memory array for read/write functionality. The functionality of a matching function, a priority encoding function, a match flag function, and a multiple match flag function of the CAM is tested. The functionality of an invalidate data function and a valid data restricted search function is also tested.
