    摘要: Circuitry is provided that closely emulates biological neural responses. Two astable multivibrator circuits (AMCs), each including a negative differential resistance device, are coupled in series-circuit relationship. Each AMC is characterized by a distinct voltage-dependant time constant. The circuitry exhibits oscillations in electrical current when subjected to a voltage equal to or greater than a threshold value. Various oscillating waveforms can be produced in accordance with voltages applied to the circuitry.

    摘要: Chaotic oscillator-based random number generation is described. In an example, a circuit includes a negative differential resistance (NDR) device to receive an alternating current (AC) bias. The circuit further includes a capacitance in parallel with the NDR device, the capacitance having a value such that, in response to a direct current (DC) bias applied to the NDR device and the capacitance, a voltage across the capacitance oscillates with a chaotic period. The circuit further includes a random number generator to generate random numbers using samples of the voltage across the capacitance.

    摘要: A memristive device includes a first and a second electrode; a silicon memristive matrix interposed between the first electrode and the second electrode; and a mobile dopant species within the silicon memristive matrix which moves in response to a programming electrical field and remains substantially in place after the removal of the programming electrical field. A method for using a crossbar architecture containing a silicon memristive matrix includes: applying a programming electrical field by applying a voltage bias across a first conductor and a second conductor; a silicon memristive matrix containing mobile dopants being interposed between the first conductor and the second conductor, the programming voltage repositioning the mobile dopants within the silicon memristive matrix; and reading a state of the silicon memristive matrix by applying a reading energy across the silicon memristive matrix, the reading energy producing a measurable indication of the state of the silicon memristive matrix.
