Abstract

A method is provided that includes forming a first vertical bit line disposed in a first direction above a substrate, forming a first word line disposed in a second direction above the substrate, the second direction perpendicular to the first direction, forming a first memory cell comprising a nonvolatile memory material at an intersection of the first vertical bit line and the first word line, forming a transistor above the substrate, and forming a first bit line select device coupled between the first vertical bit line and the transistor.
