    • Disclosed is a method for preparing a mixed formulation of sustained release microspheres with various compositions by a continuous one-step process. The present method is characterized by preparing the mixed formulation of sustained release microspheres with different compositions by a continuous one-step process by continuously introducing the mixed fluids into a dryer from the two or more different fluids for preparation of sustained release microspheres containing a biodegradable polymer, a drug, an additive and a solvent with different types of contents or both of the components, by controlling the mixing ratios of the fluids according to the time, unlike a conventional method including spray-drying a mixture of microspheres containing a biodegradable polymer, a drug, an additive and a solvent with a single composition. The present method can achieve a desired drug release, which is difficult to be obtained by conventional microspheres with a single composition, by preparing microspheres by a continuous one-step process, and can simplify the conventional complex process of separately preparing several microsphere formulations and then mixing the formulations at a proper ratio to achieve a desired drug release.

    • Provided is related to a NAND flash memory device and method of reading the same, in which during a read operation, a ground voltage is applied to string and ground selection transistors of deselected cell blocks so as to increase resistance of a string line to prevent leakage currents due to a back-bias effect. A reduced bitline leakage current increases an ON/OFF current ratio between programmed and erased cells to reduce a sensing time therein, which makes a read trip range so as to prevent variation of threshold voltages due to data retention and reading disturbance. Voltages can be independently applied to source selection lines by electrically isolating source selection transistors between the cell blocks. It is available to reduce the number of source discharge transistors by electrically connecting the source selection transistors between adjacent cell blocks.
