    Abstract: A memory device includes a word line driver circuit, which can advantageously reduce gate stress on a transistor using a lower high voltage that varies with a command, and an operating method of the memory device. The memory device includes a plurality of memory blocks, provides a high voltage or the lower high voltage to a variable high voltage line in response to a block select signal, and changes a level of the lower high voltage to a low voltage level, a medium voltage level, or a high voltage level based on the command. The memory device applies the lower high voltage to gates of P-type metal oxide semiconductor (PMOS) transistors connected to a word line driving signal, which drives word lines of non-selected memory blocks among the plurality of memory blocks.

    Abstract: A method for replacing a capillary of a wire bonding apparatus that includes a holding unit that holds a capillary includes transferring a capillary replacing unit to the wire bonding apparatus by a mobile robot in response to receiving a capillary replacement start signal from the wire bonding apparatus, separating, by the capillary replacing unit, the capillary corresponding to the replacement signal from the wire bonding apparatus, and installing, by the capillary replacing unit, a new capillary in the wire bonding apparatus.
