ABSTRACT:
The present invention encompasses a method of storing ternary data that includes the steps of (1) initializing a conversion register by storing binary-to-ternary mask data in a conversion register; (2) storing ternary data in a content addressable memory (CAM) by inputting a single bit binary data to the conversion register, and converting the binary data into two bits of ternary data using the conversion register; and (3) simultaneously storing the two bits of ternary data in first and second memory cells. For subsequent searching, the method further includes the steps of searching for a match of input search binary data to the stored contents of the CAM; providing a match valid output responsive to the input search binary bits matching any of the stored contents; and generating an address corresponding to a location in the CAM where the match is found.
