Abstract

Methods and structures of a three-dimensional memory device are disclosed. In an example, the memory device includes a plurality vertical memory strings disposed through an alternating conductor/dielectric stack. Each of the memory strings includes a composite dielectric layers and a TFET semiconductor layer. The TFET semiconductor layer includes an n-type semiconductor layer and a p-type semiconductor layer.
