Abstract
According to one embodiment, a memory device includes a first electrode, a second electrode, and a variable resistance film. The variable resistance film is connected between the first electrode and the second electrode. The first electrode includes a metal contained in a matrix made of a conductive material. A cohesive energy of the metal is lower than a cohesive energy of the conductive material. A concentration of the metal at a central portion of the first electrode in a width direction thereof is higher than concentrations of the metal in two end portions of the first electrode in the width direction.
