Multilevel-Cell Phase-Change Memory: A Viable Technology

Milos Stanisavljevic, Aravinthan Athmanathan

In order for any non-volatile memory (NVM) to be considered a viable technology, its reliability should be verified at the array level. In particular, properties such as high endurance and at least moderate data retention are considered essential. Phase-ch ...
