Patent ID: 11663457

Abstract:
A non-volatile synapse circuit of a non-volatile neural network. The synapse includes: a first input signal line for providing a first input signal; a reference signal line for providing a reference signal; first and second output lines for carrying first and second output signals therethrough, and first and second cells for generating the first and second output signals, respectively. Each of the first and second cells includes: a first upper select transistor having a gate that is electrically coupled to the first input signal line; and a first resistive changing element having one end connected to the first select transistor in series and another end electrically coupled to the reference signal line. The value of the first resistive changing element may be programmable to change the magnitude of an output signal. The drain of the first upper select transistor of the first cell is electrically coupled to the first output line and the drain of the first upper select transistor of the second cell is electrically coupled to the second output line.
