Abstract
A semiconductor memory device uses a magnetic tunnel junction device (MTJ) and includes a memory cell connected between a first driving line and a second driving line and configured to store data having a data state that is determined based on a direction of a current flowing through the first and the second driving lines, and a current controlling block configured to control a supply current provided to the first and second driving lines in response to temperature information in a writing operation.
