Patent ID: 7423328

Claim:
A method for reducing word line currents in magnetoresistive random access memory (MRAM), comprising: forming an MRAM bit, comprising: forming a conductive section on a first magnetic section; forming a second magnetic section on the conductive section; forming a first metal terminal adjacent to one end of an opposite surface to the conductive section of the first magnetic section; and forming a second metal terminal adjacent to the other end of the opposite surface to the conductive section of the first magnetic section; and disposing the MRAM bit between a first word line and a second word line, wherein the first word line is capable of generating a first magnetic field to control a dipole of the first magnetic section when a first current flows on the first word line, the second word line is capable of generating a second magnetic field to control a dipole of the second magnetic section when a second current flows on the second word line, and the first or second current is derived according to a magnetic field strength squared when a distance from the first magnetic section or the second magnetic section to the corresponding word line is halved.
