Abstract

A variable resistance memory device includes a variable resistance layer and a first conductive element and a second conductive element which are spaced apart from each other on the variable resistance layer. The variable resistance layer may include a first layer and a second layer on the first layer. The first layer includes a ternary or more metal oxide containing two or more metal materials having different valences. The second layer may include silicon oxide. The variable resistance memory device may have a wide range of resistance variation due to the metal oxide in which oxygen vacancies are easily formed. The first conductive element and the second conductive element, in response to an applied voltage, may be configured to form a current path in a direction perpendicular to a direction in which the first layer and the second direction are stacked.
