Abstract
Techniques described herein are generally related to storing and retrieving data from a content-addressable memory (CAM). A data value to be stored in the CAM may be received, where the data value has two or more bits. The CAM may include a plurality of memory sets. An index corresponding to the data value may be determined. The index may be determined based on a subset of bits of the data value that correspond to an index bit set. A memory set of the CAM may be identified based on the determined index and the data value may be stored in a storage unit of the identified memory set.
