Abstract
Systems, apparatuses, and methods may provide for technology that groups a plurality of wordline drivers together and supports these grouped wordline drivers via a shared multiplexer, a shared level shifter, and/or one or more shared multi-well level shifters. In one example, such technology includes a shared multiplexer and a first and second grouped global wordline driver coupled to the shared multiplexer. The shared multiplexer is to access data state information from a plurality of memory cells. The first grouped global wordline driver is to output a first plurality of wordlines associated with a first plane. The second grouped global wordline driver is to output a second plurality of wordlines associated with a second plane, where the second plane is different than the first plane.
