In one embodiment, the write current 92 originates in {HEAD ~ bit line} 90 a and passes through the CPP cell 80 and conductive spacer 70 a in the first bit sub cell 50 a before flowing out through transistor 130 and into a conductive spacer 70 b in the second bit sub cell 50 b. Simultaneously, a current is injected to write word line which controls {TAIL ~ transistor} 130
