1. A 3D NAND Flash memory device, comprising:
a stack structure comprising tiers each comprising conductive material and insulative material vertically neighboring the conductive material;
strings of memory cells vertically extending through the stack structure;
local bit lines vertically overlying and coupled to groups of the strings of memory cells;
global bit lines vertical overlying the local bit lines;
vertical sense transistors vertically interposed between the local bit lines and the global bit lines, the vertical sense transistors having gate electrodes coupled to the local bit lines;
vertical read transistors vertically interposed between and coupled to the vertical sense transistors and the global bit lines; and
vertical write transistors at a vertical elevation of the vertical read transistors, the vertical write transistors coupled to the local bit lines and the global bit lines.
