Abstract

Resistive random access memory elements, such as phase change memory elements, may be defined using a plurality of parallel conductive lines over a stack of layers, at least one of which includes a resistive switching material. The stack may be etched using the conductive lines as a mask. As a result, memory elements may be self-aligned to the conductive lines.
