Patent abstract
Variable resistive punchthrough access methods are described. The methods include switching a variable resistive data cell from a high resistance state to a low resistance state by passing a write current through the magnetic tunnel junction data cell in a first direction. The write current is provided by a transistor being electrically coupled to the variable resistive data cell and a source line. The write current passes through the transistor in punchthrough mode.
