Abstract

A method for forming a nonvolatile PCM logic device may include providing a PCM film component having a first end contact distally opposed from a second end contact, positing a first proximity adjacent to a first surface of the PCM film component, positing a second proximity heater adjacent to a second surface of the PCM film component, wherein the first proximity heater and the second proximity heater are electrically isolated from the PCM film component. The method may further include applying a combination of pulses to one or more of the first proximity heater and the second proximity heater to change a resistance value of the PCM film component corresponding to a logic truth table. Further, the method may include simultaneously applying a first combination of reset pulses to program, or set pulses to initialize, the PCM film component, to the first proximity heater and the second proximity heater.
