Computing-in-Memory Macro with Memory Bypass Mechanism

Abstract

A computing-in-memory macro includes a memory cell, a multiplexer, and a compute cell. The memory cell is used to store weights of the computing-in-memory macro. The multiplexer is coupled to the memory cell and used to select a weight from the memory cell or a weight from an external path to output as an output weight. The compute cell is coupled to the multiplexer and used to generate an output of the computing-in-memory macro according to the output weight from the multiplexer and an activation.
