Investigation of Unified Emerging-NVM SoC Architecture for IoT-WSN Applications

In this paper, we discuss the application of emerging NVM (Non-Volatile Memory) devices such as Phase Change Memory (PCM), OxRAM (oxide based), and magneto resisitive STT-MRAM memory in System-on-Chip (SoC) used for IoT-WSN (Wireless Sensor Node) applications. We validate the concept of a unified memory architecture relying on all NVM implementation, in particular for IoT-WSN applications. Simulation and analysis for NVM based unified memory architecture are presented on MSP430 platform with Contiki, benchmarked for the Sky-Collect application. Performance parameters such asarea, write hits, write hit rate/evolution, power and latency are considered.
