Abstract:
Emerging non-volatile memory is driving a memory/storage revolution, and may fundamentally change the architecture of computer systems. In this talk, I will introduce our recent work in utilizing emerging non-volatile memory for designing and optimizing embedded systems. In particular, two techniques: PCM-FTL (Flash Translation Layer with PCM) and DHeating (Disperse Heating for Self-Healing NAND flash), will be presented. In PCM-FTL, we present for the first time a write-activity-aware NAND flash memory management scheme to effectively manage NAND flash memory and enhance the endurance of PCM-based embedded systems. In DHeating, we propose a novel wear-leveling scheme to solve the concentrated heating problem in self-healing NAND flash.
