Patent ID: 7948795

Claim:
A thin film magnetic memory device comprising: a memory array including a plurality of magnetic memory cells; a plurality of data write current lines for writing data to said magnetic memory cells, each of said data write current lines forming a data write current line pair with another neighboring one of said data write current lines; and a data write circuit for supplying a data write current to a selected data write current line of said data write current lines that corresponds to a selected memory cell of said magnetic memory cells, wherein said data write circuit guides at least a part of said data write current on said selected data write current line to an unselected data write current line of said data write current lines that forms said data write current line pair with said selected data write current line, and a magnetic field generated by said selected data write current line and a magnetic field generated by said unselected data write current line act to cancel each other in a region corresponding to at least one of the magnetic memory cells other than said selected memory cells.
