Zusammenfassung: | A memory device of embodiments includes a memory cell including: a first conductive layer; a second conductive layer; a third conductive layer provided between the first conductive layer and the second conductive layer; a variable resistance layer provided between the first conductive layer and the third conductive layer; and a switching layer provided between the third conductive layer and the second conductive layer. The switching layer contains an oxide of a first element, which is at least one element selected from a group consisting of zirconium, yttrium, tantalum, lanthanum, cerium, titanium, hafnium, and magnesium, and a compound of a second element that is at least one element selected from a group consisting of zinc, tin, gallium, indium, and bismuth and a third element that is at least one element selected from a group consisting of tellurium, sulfur, and selenium. |
