Abstract

A magnetoresistive memory device includes a memory cell including a magnetic tunnel junction element, a detector to detect a current value writable in units of the memory cell, a current value storage area, and a current controller. The current value storage area stores at least one of a maximum value and a minimum value of the writable current value detected by the detector. The current controller performs at least one control operation of an operation of controlling a write current value of the memory cell based on the maximum value and an operation of controlling a read current value of the memory cell based on the minimum value.
