Abstract:
In order to permit dense integration of a high number of stacked word lines in the semiconductor memory device, a charge pump is included in the semiconductor memory device. The charge pump makes use of a capacitor. The capacitor is implemented with respect to the dense integration. Some components are placed under the stacked word lines, and some are not under the stacked word lines. The capacity of the capacitor not under the stacked word lines is provided in part by a parallel structure.
Abstract:
Methods of operating a memory device include at least partially charging a sensing node within a page buffer of the memory device to a first precharge voltage, by sampling a trip voltage of a sensing latch within the page buffer. Thereafter, a voltage of the sensing node is boosted from the first precharge voltage to a higher second precharge voltage. Then, a voltage of the sensing node that reflects a value of data stored in a memory cell of the memory device is developed at the sensing node. The developed voltage is then transferred to the sensing latch so that data stored by the sensing latch reflects the value of data stored in the memory cell.

Abstract:
An operating method of a nonvolatile memory device includes determining whether a memory block is a selected block, and when the memory block is not the selected block, determining whether the memory block shares a block word line with the selected block. The method further includes applying an unselected block word line voltage to word lines of the memory block when the memory block shares the block word line with the selected block, and floating the word lines of the memory block when the memory block does not share the block word line with the selected block.
