Claim 10:
11. A 3D NAND Flash memory device, comprising:
a stack structure comprising conductive structures and insulative structures vertically alternating with the conductive structures;
pillar structures vertically extending through the stack structure and individually comprising semiconductor material;
a local digit line overlying the stack structure and coupled to a group of the pillar structures;
a source line overlying the local digit line;
a vertical sense transistor overlying the source line, the vertical sense transistor coupled to the source line and the local digit line;
a vertical read transistor overlying the vertical sense transistor, the vertical read transistor substantially horizontally aligned with and coupled to the vertical sense transistor;
a vertical write transistor overlying the vertical sense transistor, the vertical write transistor coupled to the local digit line; and
a global digit line overlying and coupled to each of the vertical read transistor and the vertical write transistor.
