A 639.38GOPS Hybrid-Domain Logic-Compatible Multi-Level Embedded Flash Computing-in-Memory Macro with Spike-Edge Computation

Computing in Memory (CIM) has emerged as a promising research field, significantly reducing power consumption and latency associated with massive data movement and multiply-and-accumulate (MAC) operations in edge Al devices. For battery-constrained edge devices, non-volatile memories (NVMs) are ideal due to their ability to retain neural network parameters even when powered down, ensuring rapid response time upon device wake-up. Recent studies have integrated NVM into CIM architectures using STT-MRAM and RRAM, achieving high throughput and energy efficiency. Nevertheless, NVMs necessitate specialized fabrication technologies and additional manufacturing steps, which increase process complexity and costs. As NVM processes advance, these technologies become increasingly challenging to access due to the escalating costs.
