Memory cell, pair of memory cells, and memory array

摘要

A memory cell, device, and system include a memory cell having a shared digitline, a storage capacitor, and a plurality of access transistors configured to selectively electrically couple the storage capacitor with the shared digitline. The shared digitline couples with adjacent memory cells, and the plurality of access transistors selects which adjacent memory cell is coupled to the shared digitline. A method of forming the memory cell includes forming a buried digitline in a substrate and a vertical pillar in the substrate immediately adjacent to the buried digitline. A dual gate transistor is formed on the vertical pillar with a first end electrically coupled to the buried digitline and a second end coupled to a storage capacitor formed thereto.
