According to one embodiment, a magnetic random access memory includes a write circuit to write s-bit (s is a natural number equal to 2 or greater) write data to magnetoresistive elements, and a read circuit to read s-bit read data from the magnetoresistive elements. The control circuit is configured to select one of first and second modes based on a mode selection signal, read the read data by the read circuit and write one of the write data and inversion data of the write data to the magnetoresistive elements by the write circuit based on the read data and the write data if free space of the buffer memory is equal to a fixed value or more when the second mode is selected.
