Claim 0:
1. A device for neuromorphic computing, comprising:
a first ionic redox transistor and a second ionic redox transistor, where each of the first ionic redox transistor and the second ionic redox transistor comprises:
a channel layer having a first end and a second end;
a first contact positioned at the first end of the channel layer;
a second contact positioned at the second end of the channel layer, wherein:
the first ionic redox transistor is configured to operate as a synapse in a neural network based upon a first voltage in a first range of voltages being applied between the first contact and the second contact of the first ionic redox transistor, where the channel layer of the first ionic redox transistor exhibits a substantially linear current-voltage relationship in response to the first voltage being applied between the first contact and the second contact of the first ionic redox transistor; and
the second ionic redox transistor is configured to operate as an activation function in the neural network based upon a second voltage in a second range of voltages being applied between the first contact and the second contact of the second ionic redox transistor, where the channel layer exhibits a nonlinear current-voltage relationship in response to the second voltage being applied between the first contact and the second contact of the second ionic redox transistor, the second range of voltages being higher than the first range of voltages.
