Zusammenfassung:An electronic device comprising multilevel bitlines comprising first bitlines and second bitlines. The first bitlines and the second bitlines are positioned at different levels. Pillar contacts are electrically connected to the first bitlines and to the second bitlines. Level 1 contacts are electrically connected to the first bitlines and level 2 contacts are electrically connected to the second bitlines. A liner is between the first bitlines and the level 2 contacts. Each bitline of the first bitlines is electrically connected to a single pillar contact in a subblock adjacent to the level 1 contacts and each bitline of the second bitlines is electrically connected to a single pillar contact adjacent to the level 2 contacts. Methods of forming an electronic device and related systems are also disclosed.
