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.

A self-repairing memristor (300) and methods of operating a memristor (10), (310) and repairing a memristor (10), (310) employ thermal annealing (110). The thermal annealing (110) removes a short circuit in an oxide layer (12), (312) of the memristor (10), (310). Thermal annealing (110) includes heating the memristor (10), (310) to a predetermined annealing temperature for a predetermined annealing time period. The memristor (10), (310) returns to an electrically open circuit condition after the short circuit is removed.

Apparatus and methods related to memory resistors are provided. A feedback controller applies adjustment signals to a memristor. A non-volatile electrical resistance of the memristor is sensed by the feedback controller during the adjustment. The memristor is adjusted to particular values lying between first and second limiting values with minimal overshoot. Increased memristor service life, faster operation, lower power consumption, and higher operational integrity are achieved by the present teachings.
