Abstract
A semiconductor device comprising a source, and a drain spaced apart from the source in a first direction. A channel layer is disposed radially outwards of at least one radially outer surface of the source and the drain in a second direction perpendicular to the first direction, the channel layer extending in the first direction. A memory layer is disposed on a radially outer surface of the channel layer in the second direction and extending in the first direction. A contact structure is interposed between the channel layer and at least a portion of the source and/or the drain, the contact structure having a lower resistance than the channel layer.
