Abstract
Approaches for an improved encoding scheme that allows a CAM device to selectively store, within each cell of a row of the CAM device, either a single bit of a binary value or two bits of an encoded data word encoded from the binary value. By storing two bits of the encoded data word in each CAM cell, data may be stored more efficiently and CAM systems may consume less power as compared to traditional binary CAMS when performing certain types of operations, such as exact matching and longest prefix matching. Encoded data words may be, but need not be, balanced data words which have equal number of logic high and logic low values.
