Abstract
A cell transistor includes source/drain regions formed at a lower level than part of its channel region. A select transistor has a channel region and source/drain regions formed at substantially the same level as the source/drain regions of the cell transistor. One of the source/drain regions of the cell transistor and one of the source/drain regions of the select transistor are electrically interconnected to each other in substantially the same plane.
