Abstract
A non-volatile memory device includes a conductive layer, a first electrode layer provided side by side with the conductive layer in a first direction, a second electrode layer provided between the conductive layer and the first electrode. At least a part of the second electrode on the conductive layer side has a work function smaller than a work function of the first electrode. The device further includes a first channel body extending through the first electrode layer in the first direction and a charge storage portion provided between the first electrode layer and the first channel body.
