| contents | This paper proposes a circuit configuration that addresses the issue of deviation in the multiply-accumulate (MAC) results when numerous word lines are simultaneously opened in current-based compute-in-memory (CiM) circuits. The proposed circuit solves this problem by automatically shrinking the product value according to the degree of parallelism. This circuit configuration is effective for circuit methods that calculate MAC through time integration of charge. |
