Abstract:
A global word line decoder may include a voltage switching unit and a plane switching unit. The voltage switching unit may decode a plurality of operating voltages to output a selected voltage and an unselected voltage, and the plane switching unit may receive the selected voltage and the unselected voltage, and decode the selected voltage and the unselected voltage to output decoded voltages to a global word line coupled to a selected plane, among a plurality of planes. The selected voltage may include a first pre-decoded voltage and a second pre-decoded voltage, and the plane switching unit may swap and output the first pre-decoded voltage and the second pre-decoded voltage according to a position of a selected word line.
