Microelectronic devices including control logic circuitry overlying memory arrays, and related memory devices and electronic systems

Abstract

A microelectronic device is disclosed that includes array regions individually comprising memory cells comprising access devices and storage node devices; digit lines coupled to the access devices and extending in a first direction; and word lines coupled to the access devices and extending in a second direction orthogonal to the first direction, and the word lines extend into word line exit regions. The word line exit regions are horizontally alternating with the array regions in the second direction; and sub word line driver sections are overlapping and above, and in electrical communication with the word line exit regions. Electrical communication between word lines in the word line exit regions and the sub word line driver sections vertically coupled with a vertical word line contact and other interconnections is laterally bounded within socket regions delineated by horizontal boundaries of the word line exit regions.
