Claim 0:
1. A memory device, comprising:
a substrate;
a first wiring layer extending in a first direction parallel to the substrate;
a second wiring layer extending in a second direction crossing the first direction, the second direction being parallel to the substrate;
a third wiring layer being adjacent to the second wiring layer in a third direction, the third wiring layer extending in the second direction, the third direction perpendicular to the first direction and the second direction;
a fourth wiring layer extending in the first direction, the third wiring layer being provided between the second wiring layer and the fourth wiring layer;
a first resistance changing layer connected between the first wiring layer and the second wiring layer;
a second resistance changing layer connected between the third wiring layer and the fourth wiring layer;
a first insulating layer adjacent to the first resistance changing layer in the second direction; and
a second insulating layer adjacent to the first resistance changing layer in the second direction via the first insulating layer, the first insulating layer being located between the first resistance changing layer and the second insulating layer in the second direction,
wherein the first resistance changing layer includes indium.
