Abstract
A semiconductor structure comprises a conductive bridge random access memory device and an access device connected in series with the conductive bridge random access memory device. The conductive bridge random access memory device and the access device are arranged in a vertical stack. The vertical stack has a sidewall profile that increases in width from a bottom surface of the vertical stack to a top surface of the vertical stack.
