Patent ID: 6839269

Claim:
A magnetic random access memory comprising: first interconnections; second interconnections which cross said first interconnections; memory cells which are arranged between said first interconnections and said second interconnections; a decoder configured to set a predetermined potential to a selected first interconnection, and to set a floating state to the first interconnections other than the selected first interconnection, when a read current is supplied between the selected first interconnection and a selected second interconnection; a bias circuit configured to apply a bias potential to non-selected second interconnections electrically connected to the selected first interconnection by respective memory cells, when the read current is supplied between the selected first interconnection and the selected second interconnection; a first precharge circuit configured to apply a first precharge potential to the first interconnections before setting the predetermined potential to the selected first interconnection, and setting the floating state to the first interconnections other than the selected first interconnection; and a second precharge circuit configured to apply a second precharge potential to the second interconnections before applying the bias potential to the non-selected second interconnections.
