ABSTRACT:
An electronic synapse circuit is disclosed for multiplying an analog weight signal value by a digital state signal value to achieve a signed product value as a current which is capable of being summed with other such synapse circuit outputs. The circuit employs a storage multiplying digital-to-analog converter which provides storage for the analog weight signal value. Additional circuitry permits programming different analog weight signal values into the circuit, performing four-quadrant multiplication, generating a current summable output, and maintaining the stored analog weight signal value at a substantially constant value independent of the digital state signal values.
