Abstract
Aspects of the present disclosure are directed to devices and methods for performing MAC operations using a TCAM array as a compute-in-memory (CIM) device that can enable higher computational throughput, higher performance and lower energy consumption compared to computation using a processor outside of a memory array. In some embodiments, weights in a weight matrix may be programmed in SRAMs of a TCAM bit cell array. Each SRAM may operate as a multiplier that performs a multiplication between the stored weight to an input activation value applied at a search line in the TCAM bit cell array. The two SRAMs within a TCAM bit cell may operate independently to receive independently two input activation values on their respective select lines, and to perform a multiplication operation with the stored weight in each respective SRAM.
