Abstract
A nonvolatile memory device comprises a memory cell configured to store or output data in a magneto-resistance device in response to a write current applied to a bit line and a source line. A voltage detector is configured to sense potentials loaded in the bit line and the source line. A write current controller configured to control activation of a write control signal in response to an output of the voltage detector, and a write driver configured to control amounts of write current applied to the memory cell according to the activation of the write control signal.
