20130223142 | 3D STACKED NAND FLASH MEMORY ARRAY ENABLING TO OPERATE BY LSM AND OPERATION METHOD THEREOF - This invention provides a 3D stacked NAND flash memory array and operation method thereof enabling to operate by LSM (a layer selection by multi-level operation) and to get rid of the waste of unnecessary areas by minimizing the number of SSLs needed for a layer selection though the number of layers vertically stacked is increased. | 08-29-2013 |
20140233315 | 3D STACKED NAND FLASH MEMORY ARRAY HAVING SSL STATUS CHECK BUILDINGS FOR MONITORING THRESHOLD VOLTAGES OF STRING SELECTION TRANSISTORS AND METHODS FOR MONITORING AND OPERATING THE SAME - Disclosed is a 3D stacked NAND flash memory array having SSL status check buildings for monitoring threshold voltages of string selection transistors, a monitoring method of threshold voltages of string selection transistors by the SSL status check buildings, and an operating method thereof. | 08-21-2014 |
20160064083 | NONVOLATILE MEMORY DEVICE AND METHOD OF PROGRAMMING THE SAME - A nonvolatile memory device of the inventive concept includes a memory cell array, an address decoder, a read & write circuit and control logic. The memory cell array includes a plurality of memory blocks including a plurality of cell strings, each cell string including a plurality of memory cells stacked in a direction perpendicular to a substrate. The control logic controls operations so that in a program operation, when the selected word line satisfies a precharge condition, a program voltage to be applied to the selected word line is applied before a pass voltage to be applied to an unselected word line. | 03-03-2016 |
