Abstract
To reach long operating time, Nonvolatile memory (NVM) has been applied to mobile systems in an attempt to reduce energy consumption through normally-off operation. The ReRAM device as a nonvolatile memory has shown promises in replacing current NVMs used in these applications, with orders of improvement in write speeds and read/write power than those offered by conventional Flash memories. Unfortunately, constraints related to endurance, read disturb, and resistance variations are still to be overcome for the wide usage of this device. This paper provides a review of the challenges and trends associated with the ReRAM circuits and applications used in mobile and cloud applications. © 2014 IEEE.
