Abstract
According to one embodiment, a memory device includes a stacked body. The stacked body includes first and second electrodes, and an oxide layer provided between the first and second electrodes. The second electrode includes a semiconductor layer, and a metal-containing region including at least one of first or second metallic element and being provided between at least a portion of the semiconductor layer and at least a portion of the oxide layer. The first metallic element includes at least one selected from Pt, Pd, Ir, Ru, Re, and Os. The second metallic element includes at least one selected Ti, W, Mo, and Ta. The stacked body has first and second states. The first state is obtained by causing a current to flow in the stacked body from the second toward first electrode. The second state is obtained by causing a current to flow from the first toward second electrode.
