Abstract
A method and apparatus for performing refactored multiply-and-accumulate operations is provided. A summing array includes a plurality of non-volatile memory elements arranged in columns. Each non-volatile memory element in the summing array is programmed to a high resistance state or a low resistance state based on weights of a neural network. The summing array is configured to generate a summed signal for each column based, at least in part, on a plurality of input signals. A multiplying array is coupled to the summing array, and includes a plurality of non-volatile memory elements. Each non-volatile memory element in the multiplying array is programmed to a different conductance level based on the weights of the neural network. The multiplying array is configured to generate an output signal based, at least in part, on the summed signals from the summing array.
