Abstract
A multiply accumulate circuit receives m one-bit neuron values from a first layer of a neural network system. The multiply accumulate circuit includes m non-volatile memory cells and m current sources. In addition, m current paths are defined by the m non-volatile memory cells and the m current sources collaboratively. A first current path is defined by a first non-volatile memory cell and a first current source. A first terminal of the first current source receives a first supply voltage. A second terminal of the first current source is connected with a first terminal of the first non-volatile memory cell. A second terminal of the first non-volatile memory cell is connected with an output terminal of the multiply accumulate circuit. A control terminal of the first current source receives a first one-bit neuron value.
