    • A method of fabricating a fin selector with a gated RRAM and the resulting device are disclosed. Embodiments include forming a bottom electrode layer and a hardmask on a semiconductor substrate; etching the hardmask, bottom electrode layer, and semiconductor substrate to form a fin-like structure; forming first and second dummy gate stacks on first and second side surfaces of the fin-like structure, respectively; forming spacers on vertical surfaces of the first and second dummy gate stacks; forming an ILD surrounding the spacers; removing the first and second dummy gate stacks, forming first and second cavities on first and second sides of the fin-like structure; forming an RRAM layer on the first and second side surfaces of the fin-like structure in the first and second cavities, respectively; and filling each of the first and second cavities with a top electrode.
