ABSTRACT:
A memory includes a phase change element having a first side and a second side and a first line coupled to the first side of the element. The memory includes an access device coupled to the second side of the element and a second line coupled to the access device for controlling the access device. The memory includes a circuit for precharging the first line to a first voltage and for applying a voltage pulse to the second line such that a current pulse is generated through the access device to the element to program the element to a selected one of more than two states. The voltage pulse has an amplitude based on the selected state.
