Patent ID: 7292468

Claim:
A magnetic random access memory comprising: a plurality of first magnetoresistive elements which are used as memory elements; a second magnetoresistive element which is used as a current load of a read bias circuit; a first bit line that is commonly connected to one terminal of each of the first magnetoresistive elements and one terminal of the second magnetoresistive element, a number of the first magnetoresistive elements connected to the first bit line being larger than a number of the second magnetoresistive element connected to the first bit line; a third magnetoresistive element which is used as a reference element and in which first data is recorded; a fourth magnetoresistive element which is used as the reference element and in which second data is recorded; a fifth magnetoresistive element which is used as the current load of the read bias circuit; a sixth magnetoresistive element which is used as the current load of the read bias circuit; a second bit line which is commonly connected to one terminal of each of the third magnetoresistive element, the fourth magnetoresistive element, the fifth magnetoresistive element, and the sixth magnetoresistive element; a first terminal which is connected to the other terminal of each of the first magnetoresistive elements and to which a first potential is supplied; a second terminal which is connected to the other terminal of each of the second magnetoresistive element, the fifth magnetoresistive element, and the sixth magnetoresistive element and to which a second potential different from the first potential is supplied; and a third terminal which is connected to the other terminal of the third magnetoresistive element and the other terminal of the fourth magnetoresistive element and to which a third potential different from the second potential is supplied.
