Patent ID: 7920021

Claim:
A method of applying a wire voltage to a semiconductor device including a plurality of active regions and a field region insulating the plurality of active regions, the field region including a plurality of wires, the method comprising: applying an operating voltage required for an operation of the semiconductor device to at least one of the plurality of wires; and applying a voltage lower than the operating voltage to a wire from among the plurality of wires that is adjacent to at least one of the plurality of active regions, wherein the plurality of wires are respectively connected to a plurality of word lines, and the operating voltage comprises a programming voltage, wherein the semiconductor device comprises a plurality of selection transistors respectively formed on the plurality of active regions, wherein the semiconductor device further comprises at least one of a ground select line (GSL), a source select line (SSL) and a dummy wire disposed adjacent to one of the active regions on the field region, and wherein a voltage applied to the ground select line (GSL), the source select line (SSL) and the dummy wire is equal to or less than 20 V.
