    摘要： Disclosed herein are compositions useful in forming organic active patterns that may, in turn, be incorporated in organic memory devices. The compositions comprise N-containing conjugated electroconductive polymer(s), photoacid generator(s) and organic solvent(s) capable of dissolving suitable quantifies of both the electroconductive polymer and the photoacid generator. Also disclosed are methods for patterning organic active layers formed using one or more of the compositions to produce organic active patterns, portions of which may be arranged between opposed electrodes to provide organic memory cells. The methods include directly exposing and developing the organic active layer to obtain fine patterns without the use of a separate masking pattern, for example, a photoresist pattern, thereby tending to simplify the fabrication process and reduce the associated costs.

    摘要： A method of driving a multi-state organic memory device which includes an organic memory layer between upper and lower electrodes. The method comprises continuously applying voltages having different polarities to conduct switching into a low resistance state, and applying a single pulse to conduct switching into a high resistance state. A multi-state memory is realized using one memory device, since it is possible to gain three or more resistance states, thus significantly improving integration. The method has excellent reproducibility, and the resistance state induced by multiple pulses has an excellent nonvolatile characteristic.

    摘要： A startup control method of a BLDC motor is disclosed. The method can control the BLDC motor to prevent the generation of a transient current such that the vibration of the BLDC motor can be reduced at the startup stage and perform a stable conversion into a senseless operation mode such that the startup failure rate of the BLDC motor can be reduced. The startup control method includes commutating a current applied to stator windings according to a rotor position. The method of operating the BLDC motor includes a rotor position that is forcibly aligned and so that phase commutation is performed, a back-electromotive force (back- emf) is detected from a lead voltage of a phase of a voltage which is not applied thereto after performing phase commutation and a determination is performed as to whether the detected back-emf is in a rising interval. The lead voltage of the phase of the voltage which is not applied thereto is integrated, such that if the back-emf is in a rising interval and if an instance that the integration result is greater than a predetermined value a phase commutation time point is setand conversion into a senseless operation mode is performed if the back-emf detected from the lead voltage is in a stable interval, based on a frequency of the voltage applied to the stator winding.
