Abstract
On-chip non-volatile compute-in-memory (nvCIM)
enables artificial intelligence (AI)-edge processors to perform
multiply-and-accumulate (MAC) operations while enabling the
non-volatile storage of weight data in power-off mode to enhance
energy efficiency. However, the design challenges of nvCIM-
based AI-edge processors include: 1) lack of a nvCIM-friendly
computing flow; 2) a tradeoff between usage of memory devices
versus process variations, computing yield and area overhead;
3) long computing
