Abstract:
1. A device comprising: a substrate; a well of a first polarity in the substrate; a shallow trench isolation (STI) region formed in the substrate extending partially into the well; bands of a second polarity in the substrate, over the well, at opposite sides of the STI region; an area of the first polarity at a top surface of the substrate over each band; an area of the second polarity in the substrate over each band, adjacent each area of the first polarity and remote from the STI region; a recess in a top portion of the STI region, wherein a bottom surface of the recess is above a top surface of the band; a resistive random access memory (RRAM) liner on side and bottom surfaces of the recess; and a top electrode in the recess.
