摘要：
A link portion between a first electrode and a second electrode includes a semiconductor link portion and a metal semiconductor alloy link portion comprising a first metal semiconductor alloy. An electrical pulse converts the entirety of the link portion into a second metal semiconductor alloy having a lower concentration of metal than the first metal semiconductor alloy. Due to the stoichiometric differences between the first and second metal semiconductor alloys, the link portion has a higher resistance after programming than prior to programming. The shift in electrical resistance well controlled, which is advantageously employed to as a programmable precision resistor.
