Abstract:
A synaptic semiconductor device and neural networks using the same operates with an ultrahigh speed through a tunneling operation by a semi-floating gate and applies pre- and post-synaptic signals to first and second control gates directly.

Claim (Index 1):
A synaptic semiconductor device comprising:\n a channel/source stack structure vertically arranged in the order of a channel region and a source region from a semiconductor substrate; a floating gate and a control gate spaced apart from a sidewall of the channel/source stack structure interlaying with a gate insulating film on the semiconductor substrate; and a drain region formed in the semiconductor substrate adjacent to the control gate, wherein the gate insulating film is also provided between the control gate and the semiconductor substrate, wherein a drain extension having a conductivity type equal to that of the drain region is formed in the semiconductor substrate from the drain region to a lower portion of the channel/source stack structure, and wherein the floating gate is formed of a semiconductor material having a conductivity type opposite to that of the drain region and is a semi-floating gate having a protruding portion that contacts the drain extension by a PN junction.
