Abstract

A three-dimensional (3D) memory device and a fabricating method thereof are disclosed. The 3D memory device can comprise an array of memory cells. Each memory cell can comprise a capacitor and a vertical transistor. The vertical transistor can comprise a semiconductor body extending in a vertical direction and in contact with the capacitor, and a three-sided gate structure surrounding the semiconductor body from three lateral directions. The 3D memory device can further comprise a memory controller configured to control the array of memory cells.
