Abstract
A method for accessing data on a magnetic memory is provided, wherein the data is accessed in a toggle mode. A first current line and a second current line are used for providing operation currents. The data accessing method includes a data changing operation for changing a data stored in a magnetic memory cell. During a first stage, a current in a first direction is supplied to the first current line, and a current in the first direction is simultaneously supplied to the second current line. During a stage before stopping supplying magnetic field, a current in the first direction is supplied to the first current line, and a current in the first direction is simultaneously supplied to the second current line to offset at least a portion of the biased magnetic field.
