| 20110241756 | FAST TIME-TAGGED EVENT DETECTION USING RESISTIVE SWITCHING DEVICES - A system for event detection uses a resistive switching device to record a detected event. The resistive switching device has a resistance adjustable by means of an applied voltage. The operation of the resistive switching device is controlled by a controller, which is configured to apply a switching voltage to the resistive switching device at a start time, and turn off the switching voltage in response to an event signal indicative of occurrence of an event. The resistance value of the resistive switching device resulting from the application of the switching voltage is indicative of the detection of the event and also the time of the occurrence of the event. | 10-06-2011 |

| 20110279135 | MEMRISTOR ADJUSTMENT USING STORED CHARGE - Methods and apparatus pertaining to memory resistors are provided. Electronic circuitry determines energy for changing a non-volatile resistance of a memristor from a present value to a target value. An electric charge corresponding to the energy is stored. An electric pulse is applied to the memristor using the stored charge. The newly adjusted resistance of the memristor is sensed and compared to the target value. Additional electric pulses can be applied in accordance with the comparison. Memristor adjustment by way of feedback control is thus contemplated by the present teachings. | 11-17-2011 |
