Patent ID: 10840249

Abstract:
An integrated circuitry construction comprises a first area and a second area aside the first area. Laterally-alternating first and second conductive lines extend from the first area into the second area. The second conductive lines extend laterally deeper into the second area on one side of the first area than the first conductive lines and comprise pairs of immediately-laterally-adjacent of the second conductive lines. Insulative material is in the second area laterally between the immediately-laterally-adjacent second conductive lines in individual of the pairs. An elevationally-extending wall of insulator material is within the insulative material in the second area. The wall extends laterally between immediately-laterally-adjacent of the second conductive lines within the respective individual pair and laterally all across the first conductive line that is laterally between the immediately-laterally-adjacent second conductive lines within the respective individual pair. The insulator material is of different composition from that of the insulative material. Third conductive lines are in the second area above the second conductive lines. The third conductive lines individually directly electrically couple with individual of the second conductive lines through an elevationally-extending conductive via in the second area.
