  • Publication number: 20160268340
    Abstract: A non-volatile data storage device comprises pairs of immediately adjacent and isolated-from-one-another local bit lines that are independently driven by respective and vertically oriented bit line selector devices. The isolation between the immediately adjacent and isolated-from-one-another local bit lines also isolates from one another respective memory cells of the non-volatile data storage device such that leakage currents cannot flow from memory cells connected to a first of the immediately adjacent and isolated-from-one-another local bit lines to memory cells connected to the second of the pair of immediately adjacent and isolated-from-one-another local bit lines. A method programming a desire one of the memory cells includes applying boosting voltages to word lines adjacent to the bit line of the desired memory cell while not applying boosting voltages to word lines adjacent to the other bit line of the pair.

  • Patent number: 9322881
    Abstract: An impulse voltage generator uses a predetermined rectangular waveform signal and a high voltage to generate an impulse voltage. The high voltage is obtained by boosting an instruction voltage of the rectangular waveform signal on a per-cycle basis. A partial discharge frequency calculation section receives detection signals based on partial discharges occurring in an object to be measured by the application of the impulse voltage and counts the detection signal on a per-cycle basis as a partial discharge frequency. An application voltage signal observation circuit observes an application voltage signal indicating the impulse voltage applied to the object to be measured. In a first cycle in which the partial discharge frequency reaches a specified frequency or more, a voltage value acquiring section sets, as a partial discharge starting voltage, the peak value of the voltage indicated by the application voltage signal output from the application voltage signal observation circuit.
