A diode-free magnetic random access memory comprises two sets of conductive
lines, an array of magnetic tunnel junctions at each intersection, and a p
eripheral circuitry. Such a simplified diode-free architecture described in
this letter overcomes the diode-area constraint in the prior art and achie
ves a significant breakthrough in storage density. (C) 2000 American Instit
