Analog Iterative Programming for Multilevel Phase Change Memory

Iterative programming is essential for multilevel phase change memory (PCM). An analog iterative programming scheme is proposed which has the potential for significant improvements in programming bandwidth as well as power and area efficiency. A system-level model of the PCM cell is used to simulate the programming scheme. Moreover, experimental results using discrete electronics and PCM cell devices are presented that demonstrate the efficacy of this programming scheme. This programming concept could significantly enhance the potential of multilevel PCM to play a broad role in the entire memory/storage system hierarchy and even in future neuromorphic hardware.
