US Patent 11397544 Multi-terminal neuromorphic device

A neuromorphic memory element comprises a memristor, a plurality of the neuromorphic memory elements and a method for operating the same may be provided. The memristor comprises an input signal terminal, an output signal terminal, and a control signal terminal, and a memristive active channel comprising a phase change material. The memristive active channel extends longitudinal between the input signal terminal and the output signal terminal, and a control signal voltage at the control signal terminal is configured to represent volatile biological neural processes of the neuromorphic memory element, and a bias voltage between the input signal terminal and the output signal terminal is configured to represent non-volatile biological neural processes of the neuromorphic memory element.
