Abstract:
1. A thin film magnetic memory device comprising: a plurality of memory cells arranged in rows and columns, and each storing data written in response to application of first and second data write magnetic fields; a plurality of write word lines provided corresponding to said rows for passing, in a predetermined direction, a first data write current producing said first data write magnetic field in a selected row, respectively; a plurality of bit lines provided corresponding to said columns for passing, in a direction in accordance with a level of write data, a second data write current producing said second data write magnetic field in a selected column, respectively; and a write word line drive circuit for passing said first data write current only in a portion of selected one of said write word lines corresponding to a selected row, wherein said each of the plurality of write word lines has a first node corresponding to one end portion, a second node corresponding to the other end portion, and one or more intermediate nodes, said write word line drive circuit is configured to pass said first data write current such that the one or more intermediate nodes correspond to at least one of a starting point and an end point of said first data write current, and said intermediate nodes are not the point of connection of said plurality of memory cells and said plurality of write word lines.
