Zusammenfassung:A system includes a cross-point memory array and a decoder circuit coupled to the cross-point memory array. The decoder circuit includes a predecoder having predecode logic to generate a control signal and a level shifter circuit to generate a voltage signal. The decoder circuit further includes a post-decoder coupled to the predecoder, the post-decoder including a first stage and a second stage coupled to the first stage, the control signal to control the first stage and the second stage to route the voltage signal through the first stage and the second stage to a selected conductive array line of a plurality of conductive array lines coupled to a memory array.
