Abstract
A phase change memory, system, and method for gradually changing the conductance and resistance of the phase change memory while preventing resistance drift. The phase change memory may include a phase change material. The phase change memory may also include a bottom electrode. The phase change memory may also include a heater core proximately connected to the bottom electrode. The phase change memory may also include a set of conductive rings surrounding the heater core, where the set of conductive rings comprises one or more conductive rings, and where the set of conductive rings are proximately connected to the phase change material. The phase change memory may also include a set of spacers, where a spacer, from the set of spacers, separates a portion of a conductive ring, from the set of conductive rings, from the heater core.
