DUO CONTENT ADDRESSABLE MEMORY (CAM) USING A SINGLE CAM

摘要

Disclosed is a content addressable memory (CAM). The content addressable memory array includes a memory array and a data match module. The memory array includes multiple memory rows. Each memory row is configured to store a first data word and a second data word. The data match module includes a first match circuitry configured to compare a first match word to the first data word of a memory row, and to generate a first match output based on the comparison between the first match word and the first data word of the memory row. The data match module further includes a second match circuitry configured to compare a second match word to the second data word of the memory row, and to generate a second match output based on the comparison between the second match word and the second data word of the memory row.
