Memory including two access devices per phase change element

摘要

A memory includes a bit line and a phase change element. A first side of the phase change element is coupled to the bit line. The memory includes a first access device coupled to a second side of the phase change element and a second access device coupled to the second side of the phase change element. The memory includes a circuit for precharging the bit line and one of selecting only the first access device to program the phase change element to a first state and selecting both the first access device and the second access device to program the phase change element to a second state.
