Abstract
A switching architecture provides input voltage signals from input voltage lines to a plurality of global word lines connected to word lines of a memory array in a memory device. The switching architecture includes a first switching block receiving a first set of positive voltages used to bias unselected word lines and being connected to a first output line providing a first output bias voltage, and a second switching block receiving a second set of positive voltages and a third set of negative voltages used to bias selected word lines and being connected to a second output line providing a second output bias voltage. A plurality of final switches are input connected to the first and second output lines and are output connected to a respective global word line.
