ABSTRACT:

As technology scales, the conventional memory technologies, such as SRAM and DRAM, face some severe design challenges, like the increasing leakage power and the decreasing reliability. In recent years, some emerging nonvolatile memories, such as resistive random access memory (ReRAM) and spin-transfer torque magnetic RAM (STT-RAM), have been developed, and widely studied as the replacements for SRAM and DRAM in next-generation memory system design thanks to some of their nice features such as zero leakage power. They have other nice characteristics that have not been well exploited yet such as non-volatility.

This talk will mainly introduce two recent projects that utilize the unique features of ReRAM and multi-level cell (MLC) STT-RAM. The first project leverages the computation capability of ReRAM crossbar structure, and designs a novel processing-in-memory architecture to accelerate neural network applications in ReRAM based main memory. The second project takes advantage of the non-volatility and the read and write characteristics of MLC STT-RAM, and designs a fast and energy-efficient local checkpointing scheme in MLC STT-RAM based main memory. The speaker will briefly introduce her other related projects and share her plan for the future work at the end.
