    Abstract

    This paper describes the trends in recent CIM-SRAM designs utilizing such analog and digitally-intensive approaches. In an analog CIM-SRAM design,the inputs/activations are transformed into analog voltage or pulsewidth and applied on wordlines and/or bitlines. Multi-bit MAC computations often involve peripheral data converter circuits which need to be optimized significantly to minimize the area and energy overheads. On the other hand, digitally-intensive CIM-SRAM approaches try to avoid analog circuits by implementing smaller bit-width wordline/bitline computations and utilize sense amplifiers for performing basic logic operations and/or employ small digital logic block next to the SRAM column I/O circuits forming compute-in/near SRAM designs.Key design trends in both approaches and qualitative comparisons is presented with a perspective on future CIM-SRAM designs.
