Abstract:
1. A magnetic random access memory comprising: memory cells which are connected in parallel with each other and store data by using a magnetoresistive effect; a write bit line which is placed near said memory cells and extends in a first direction; first and second write bit line drivers/sinkers which supply a write current to said write bit line or absorb the write current from said write bit line; a first switch connected between one end of said write bit line and said first write bit line driver/sinker; a second switch connected between the other end of said write bit line and said second write bit line driver/sinker; a read bit line which is connected to one terminal of each of said memory cells and extends in the first direction; a read circuit which supplies a read current to said read bit line; a third switch connected between said read bit line and said read circuit; and write word lines extending in a second direction perpendicular to the first direction.
