ABSTRACT:
An apparatus and method are disclosed for detecting multiple hits in CAM arrays. A binary address value is stored for each entry of the CAM array and is output to identify the matching entry for a single hit. However, to facilitate multiple hit detection, both the true and complement components of this address are stored and output to determine whether or not a multiple hit occurred. If a multiple hit occurs (e.g., more than one address location has been matched), all the bits that make up the binary address and the complement will not be complements of each other and a multiple hit condition can be detected by XORing each bit of an address location value with the complement of that address location value. If the XORed bits are equal to “1”, then a single hit has occurred. Otherwise, a multiple hit has occurred.
