Alternatively, the write current 92 may flow in the opposite direction of write current 92 and move from bit line 90 b to bit line 90 a when a voltage is applied to transistor 130 that forces a current to flow from {HEAD ~ conductive spacer} 70 b to {TAIL ~ conductive spacer} 70 a as understood by those skilled in the art
