A magnetic memory device includes a memory cell array, a counter circuit and a control circuit. The memory cell array includes a memory cell including a magneto resistive element in which writing is performed by current in a first direction or current in a second direction which is an opposite direction to the first direction. The memory cell array includes a first word line and a first bit line, both connected with the memory cell. The counter circuit counts the number of writing times in the first direction while the counter circuit is in electrical connection with the magneto resistive element. The control circuit performs writing in the second direction in the memory cell when the number of consecutive writing times in the first direction reaches a threshold number of times while the control circuit is in connection with the memory cell array.

Magnetic memory device

A magnetic memory device includes a memory cell array comprising memory cells including magnetic tunnel junction elements. Each memory cell is electrically connected between a source line and a bit line. A control circuit is configured to perform a screening test on the memory cell array before writing data to the memory cell array. The screening test determines whether an abnormal cell is present in the memory cell array. The controller applies a first writing voltage to the write data to the memory cell array if the abnormal cell is not present, or applies a second writing voltage to write data to the memory cell array if the abnormal cell is present. The second writing voltage is different from the first writing voltage.
