Abstract:
1. A thin film magnetic memory device, comprising: a memory array having a plurality of magnetic memory cells arranged in every other memory cell row and every other memory cell column such that each memory cell of said plurality of memory cells is separated from another by an adjoining memory cell location in a row direction and an adjoining memory cell location in a column direction, each of said plurality of magnetic memory cells including a plurality of write word lines provided corresponding to the respective rows of the magnetic memory cells, and selectively activated according to a row selection result in a data write operation so as to cause said first data write current to flow therethrough; a plurality of read word lines provided corresponding to the respective rows, for actuating the corresponding memory cell selection gate according to a row selection result in said data read operation; a plurality of write data lines provided corresponding to the respective columns of the magnetic memory cells, for causing said second data write current to flow therethrough in said data write operation; and a plurality of read data lines provided corresponding to the respective columns, for causing said data read current to flow therethrough in said data read operation, wherein adjacent magnetic memory cells share a corresponding one of at least one of said plurality of write word lines, said plurality of read word lines, said plurality of read data lines and said plurality of write data lines.
