摘要： There are provided a sense amplifier for sensing a multilevel cell and a memory device including the same. The sense amplifier is configured to sense the most significant bit (MSB) and the least significant bit (LSB) of 2-bit data a cell voltage stored in a memory cell as the most significant bit (MSB) and the least significant bit (LSB) of 2-bit data. The sense amplifier senses the MSB of the 2-bit data in a state in which a bit line is electrically disconnected from a holding bit line of the sense amplifier and senses the LSB of the 2-bit data in a state in which the cell bit line is electrically connected to the holding bit line. The sense amplifier is configured to equalize a pair of bit lines of the sense amplifier before sensing the MSB and the LSB of the 2-bit data. The sense amplifier is configured to restore to the memory cell the cell voltage corresponding to the sensed MSB and LSB of the 2-bit data.

摘要： Provided is an electronic device including a first body, a second body, and a support member. The second body is separably installed such that at least a part of an area thereof overlaps a mounting surface of the first body. The support member is installed on the first body to open at a predetermined cradling angle, thereby cradling the second body on the first body to improve user convenience, maximize portability when the electronic device is coupled, and protect the electronic device from external forces, thereby contributing to improvement of reliability of the electronic device.
