Abstract
A method is disclosed for forming a memory device having buried access lines (e.g., wordlines) and buried data/sense lines (e.g., digitlines) disposed below vertical cell contacts. The buried wordlines may be formed trenches in a substrate extending in a first direction, and the buried digitlines may be formed from trenches in a substrate extending in a second direction perpendicular to the first direction. The buried digitlines may be coupled to a silicon sidewall by a digitline contact disposed between the digitlines and the silicon substrate.
