ABSTRACT:
A circuit and method is provided for implementing a content addressable memory circuit (100) in which at least one output word is produced which corresponds to the content of a match word. A binary search logic circuit (103) binarily searches the memory array (101) to find a match entry with multiple words whose content is equal to that of an input value with multiple words. The amount of words in each match entry is user programmable and defined at startup. The CAM (100) is capable of masking out words to be compared or outputted and allows overlapping of words to be compared and outputted. Output signals indicate whether a match has been found.
