Abstract
Apparatuses and methods for performing lookup operations are provided. A content addressable memory (CAM) module disposed on a first chip includes one or more content addressable memories. A random access memory (RAM) module disposed on the first chip is configured to receive a memory address from the CAM modules, the memory address being based on a search key received by the CAM module. The RAM module includes one or more random access memories configured to store data entries and counter values or timestamps for respective ones of the data entries. The RAM module also includes logic that is configured to compute the counter values or timestamps. The RAM module is configured to output a data entry corresponding to the search key, the data entry being stored in the one or more random access memories at the memory address, and a counter value or timestamp for the data entry.
