Abstract
A memory device includes first and second conductive layers aligned in a first direction; a memory pillar including first and second portions serving as first and second memory cells in a region where the second conductive layer overlaps the first conductive layer in the first direction; a first insulating member arranged between the first and second conductive layers in a region where the second conductive layer does not overlap the first conductive layer in the first direction; and a second insulating member intersecting with the first conductive layer in a region where the second insulating member overlaps the first insulating member in the first direction. An upper end of the second insulating member is separated from a lower end of the first insulating member.
