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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for variable resistive memory punchthrough access method","description":"Variable resistive punchthrough access methods are described.
