Abstract
A neural network using a cross-point array is provided along with a pattern readout method thereof. Resistive memory devices are stacked vertically to form the neural network as synaptic devices. The connection strength of the signal passing between two neurons is controlled by the positive and negative conductance of the resistive memory devices and it is possible to recognize and readout patterns by learning in the cross-point array.
Claims10
A neural network composed of a plurality of synaptic devices,
- wherein the neural network has a cross-point array vertically stacked with a plurality of conductive lines intersecting each other,
- wherein the conductive lines are stacked in three or more layers, and
- wherein the synaptic devices are arranged symmetrically with one of the conductive lines disposed therebetween.
