Abstract
A phase change memory may be made with improved speed and stable characteristics over extended cycling. The alloy may be selected by looking at alloys that become stuck in either the set or the reset state and finding a median or intermediate composition that achieves better cycling performance. Such alloys may also experience faster programming and may have set and reset programming speeds that are substantially similar.
