As conventional memory technologies such as DRAM run into the scaling wall, architects and system designers are forced to look at alternative technologies for building future computer systems. Several emerging Non-Volatile Memory (NVM) technologies such as PCM, STT-RAM, and Memristors have the potential to boost memory capacity in a scalable and power-efficient manner. However, these technologies are not drop-in replacements and will require novel solutions to enable their deployment. Even the prime candidates among these technologies have their own set of challenges such as higher read latency (than DRAM), much higher write latency, and limited write endurance.

In this talk, I will discuss our research addressing these challenges.  Our solutions include: hybrid memory systems, start-gap wear leveling, online attack detection, and efficient error correction. These solutions are applicable to a wide variety of emerging NVM technologies, and lay the groundwork for enabling their adoption in a broad spectrum of computer systems.
