Abstract: A nonvolatile memory device that performs two-way channel precharge during programming is provided. A program operation of the nonvolatile memory device simultaneously performs a first precharge operation in a bit line direction and a second precharge operation in a source line direction on channels of a plurality of cell strings before programming a selected memory cell to initialize the channels. The first precharge operation precharges the channels of the plurality of cell strings using a first precharge voltage applied to the bit line through first and second string selection transistors, and the second precharge operation precharges the channels of the plurality of cell strings using a second precharge voltage applied to the source line through first and second ground selection transistors.

Abstract: A housing of an electronic device according to an embodiment may include a combination of at least two housings, and the entire size or length of the electronic device may change according to relative movement between the housings. The electronic device may comprise: a flexible display configured to expand or contract according to a change in size of the electronic device. A portion of the flexible display may be inserted into the housing when the housing contracts and may be drawn out of the housing when the housing expands. The electronic device may comprise a distance sensor and/or an expansion sensor. The distance sensor is configured to measure a change in a relative distance of the housing, and the expansion sensor senses a contraction or expansion state of the housing, thereby contributing to correcting data measured by the distance sensor. The electronic device employing the distance sensor and/or the expansion sensor can accurately sense the size of an externally visible portion of a display and can display a screen appropriate to the size of the visible portion of the display.
