Abstract
A memory device is described. A first conductive layer extends in a first direction. A second conductive layer extends in the first direction. A third conductive layer extends in a second direction intersecting the first direction. A first oxide region is disposed between the first conductive layer and the third conductive layer and between the second conductive layer and the third conductive layer. A semiconductor region is disposed between the first conductive layer and the first oxide region and between the first conductive layer and the second conductive layer. A second distance between the semiconductor region, which is disposed between the first conductive layer and the second conductive layer, and the third conductive layer, is longer than a first distance between the semiconductor region, which is disposed between the first conductive layer and the first oxide region, and the third conductive layer.
