A synapse cell for use in providing a weighted connection strength is disclosed. The cell employs a four-quadrant multiplier and a pair of floating gate devices. Various charge levels are programmed onto the floating gate devices, establishing weight and reference levels. These levels affect the current...http://www.google.com.tw/patents/US4950917?utm_source=gb-gplus-share專利 US4950917 - Semiconductor cell for neural network employing a four-quadrant multiplier
