Patent ID: 8693238

Claim:
A magnetic random access memory utilizing spin transfer, comprising: a memory cell array comprising a plurality of memory cells, each memory cell comprising a magnetic resistance element and a selection transistor having one of source/drain electrodes connected with one end of said magnetic resistance element; a plate line to which one of the source/drain electrodes is connected, or the plate line being connected to the other end of said magnetic resistance element; and a word driver configured to drive a word line which is connected with a gate electrode of said selection transistor, wherein said word driver changes a drive voltage of said word line for a write data to be written in said magnetic resistance element, based on the write data supplied to said word driver, and the plate line has a predetermined voltage that is a middle voltage between a power supply voltage and a ground voltage, wherein said word driver drives said word line with a first drive voltage that is the power supply voltage, when the write data is a first data, and said word driver drives said word line with a second drive voltage that is the predetermined plate line voltage and which is higher than the first drive voltage, when the write data is a second data complementary to said first data.
