Paper Title: Design of PRAM-based Persistent NVDIMM Controllers to Prepare the Data Age

Paper Abstract: Data is exploding and generated more in just the last year than in the entire previous history of industry. The data volumes are growing faster than ever before and expected to keep increasing more than hundreds Zeta-bytes for the next decade. While this big data explosion can open to new semiconductor business opportunities, memory scaling is unfortunately limited due to a low storage core reliability and significant core-to-core interference. In this talk, we will uncover a prototype of novel persistent NVDIMM controller that deals with a new type of Phase Change RAM (PRAM) and discuss several innovative concepts using the PRAM-based persistent NVDIMM controller to bridge the gap between storage demand and supply at the data age 2025. The demonstration of this presentation will include our several empirical evaluation results and the potential benefits brought by the controller's smart technologies, implemented in a FPGA prototype by being aware of new memory's unique memory-level characteristics and interfaces. Lastly, we will also demonstrate a use-case scenario that automates SSD firmware with our persistent NVDIMM controller, which is also implemented in our real FPGA hardware prototype.
