Abstract
According to one embodiment, a magnetic random access memory includes a write circuit to write complementary data to first and second magnetoresistive elements, and a read circuit to read the complementary data from the first and second magnetoresistive elements. The control circuit is configured to change the first and second bit lines to a floating state after setting the first and second bit lines to a first potential, and change a potential of the first bit line in the floating state to a first value in accordance with a resistance value of the first magnetoresistive element and a potential of the second bit line in the floating state to a second value in accordance with a resistance value of the second magnetoresistive element by setting the common source line to a second potential higher than the first potential.
