Abstract:
A magnetic random access memory comprising:a plurality of memory elements arranged in a matrix so that the electric resistance of each of the memory elements can be switched to a high-resistance state and a low-resistance state by selecting the magnetization direction of a magnetic layer; a plurality of bit lines arranged for the respective rows of the matrix; and a plurality of write lines arranged for the respective columns of the matrix so as to cross the bit lines, ends of the memory elements being connected to any one of the bit lines; wherein information is written in the memory elements arranged in a same row or column by performing once each of the first information writing step of applying a first magnetic field to put the memory elements in the high-resistance state, and the second information writing step of applying a second magnetic field to the memory elements in which the first information has not been written to write information in all memory elements in the same row under recording of information.
