Abstract
A semiconductor memory device includes a memory cell array of nonvolatile memory cells having a variable resistance element, and a conductor line array capable of generating a compensation magnetic field for the nonvolatile memory cells. A current driver selectively supplies current to conductive lines, a magnetic field sensor senses an applied external magnetic field and generates external magnetic field information, and a controller controls generation of the compensation magnetic field in response to the external magnetic field information.
