Abstract
According to one embodiment, a nonvolatile semiconductor memory device comprises a semiconductor substrate, and a memory cell which is arranged on the semiconductor substrate and comprises a variable resistance element. The variable resistance element comprises a laminated structure including a phase-change element which has at least two different crystalline resistance states by varying a crystalline state, and a magnetoresistive element which has at least two different magnetization resistance states by varying a magnetization state, and applies or does not apply a magnetic field to the phase-change element in accordance with the magnetization state.
