Abstract
A non-volatile memory device includes a first electrode layer, a second electrode layer adjacent to the first electrode layer, a third electrode layer adjacent to the second electrode layer, a fourth electrode layer adjacent to the third electrode layer, and a channel body extending through the first electrode layer, the second electrode layer, the third electrode layer and the fourth electrode layer in a first direction. The device further includes a circuit electrically connected to the first electrode layer, the second electrode layer, the third electrode layer, the fourth electrode layer, and the channel body. The circuit providing the second electrode layer with a first potential, the third electrode layer with a second potential higher than the first potential, the fourth electrode layer with a third potential between the first potential and the second potential and the channel body with a potential rising in the first direction.
