Dual loop sensing scheme for resistive memory elements
A method and apparatus for sensing a resistive state of a resistive memory element includes producing a first current related to a resistance of a memory cell. The first current is added to a second current during a first sensing time and subtracted from a third current during a second sensing time. The first, second and third currents are integrated over time using a capacitor, and a resulting voltage signal on the capacitor is timed using a clocked counter. A time average value of a digital output of the clocked counter is then related to the resistance of the memory cell, and hence to the resistive state of the resistive memory element.

The invention provides miniaturized lateral flow chromatographic and lateral flow chromatographic microarray devices (LFM). The miniaturization of lateral flow nucleic acid detection achieved by the present invention offers reduced reagent use, femtomole sensitivity, excellent linear dynamic range, and rapid detection. Moreover, the small feature sizes of capture oligonucleotides renders the potential information capacity of the platform comparable to more traditional spotted fluorescence microarrays as well as improving sensitivity. The LFM devices exemplified herein enable analytes to be detected within 10 seconds from the time of sample introduction to the LFM device. Sample volumes may be as low as about 10 microliters, significantly reducing assay costs and ameliorating reagent storage logistics. Additionally, the miniaturization of lateral flow opens the door to highly multiplexed assays, allowing many proteins or nucleic acids to be detected in a single assay.
