    Abstract: A method is provided. The method includes identifying whether an amount of change in the pressure detected through an atmospheric pressure sensor is greater than or equal to a specified first threshold, in response to the amount of change in the pressure being greater than or equal to the first threshold, waking up a biometric sensor module including a plurality of electrodes in which some of the plurality of electrodes are disposed to come into contact with a body part of a user when the electronic device is worn, and others thereof are disposed to not come into contact with a body part of the user when the electronic device is worn, and identifying whether an interrupt signal, indicating that a state in which the plurality of electrodes are electrically connected is maintained for a specified first time or more, is received from the biometric sensor module.

    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.

    Abstract: Various embodiments provide a device and method for detecting a folding angle of an electronic device. The electronic device includes: a first housing structure connected to a hinge structure; a second housing structure folded about the hinge structure relative to the first housing structure; a first motion sensor module disposed in the first housing structure; a second motion sensor module disposed in the second housing structure; a magnetic force sensor module disposed in the first housing structure; a magnetic body disposed in the second housing structure; and at least one processor. The at least one processor is configured to: identify a folded first angle between the first housing structure and the second housing structure based on the first motion sensor module and the second motion sensor module, and a first index associated with a state of the first angle, identify a folded second angle between the first housing structure and the second housing structure based on the magnetic force sensor module, and a second index associated to a state of the second angle, and determine the folded angle between the first housing structure and the second housing structure based on at least one of the first angle or the second angle selected based on the first index and the second index.
