Abstract
A multiply-accumulate (MAC) device for compute-in-memory (CIM) includes an input driver configured to provide a plurality of input signals including a first input signal and a second input signal. A lookup table (LUT) stores or accesses a plurality of CIM weight signals including a first CIM weight signal and a second CIM weight signal. The LUT is configured to receive the first input signal and the second input signal and provide a sum output based on the first and second input signals and the first and second CIM weight signals.
