ABSTRACT:
A magnetic memory device includes a plurality of word lines, a plurality of bit lines arranged to intersect with the word lines, an MRAM cell array including a plurality of magnetic random access memory (MRAM) cells arranged at intersection portions between the word lines and the bit lines, a read current source which supplies a read current to the MRAM cells in a read mode, a sense amplifier which detects terminal voltages of the MRAM cells generated by the read current to generate a detection output signal, a latch circuit which latches the detection output signal to output read data, and a data write circuit which supplies a write current to the MRAM cells depending on write data in a write mode to perform writing and which supplies the write current to the MRAM cells depending on the read data in the read mode to perform rewriting.
