This may maintain continuum behavior while reducing random cell-to-cell variability that is often encountered at nanoscopic scales. In another embodiment, such vertical memory cell structures may be formed in multiple-tiers to define a three-dimensional RRAM memory array. Further embodiments also provide a spacer pitch-doubled RRAM memory array that integrates vertical memory cell structures.
