Symposium M, 'Materials and Technology for Nonvolatile Memories', was held November 30-December 5 at the 2014 MRS Fall Meeting in Boston, Massachusetts, which was a follow up of previous symposia on nonvolatile memories. Main research areas featured in Symposium M were advanced Flash memories, organic memories, resistive switching memories (ReRAM), magnetoresistive random access memories (MRAM), ferroelectric random access memories (FeRAM), phase-change memories, as well as emerging materials and technologies for nonvolatile memories. In addition, a highly successful one-day tutorial session,...
