During Flash Memory Summit 2013, Sony delivered a lecture on ReRAM (resistive random-access memory) - a technology Sony has been developing together with Micron. Sony hopes to start producing 16Gb ReRAM chips by 2015 (20nm) for the storage-class memory (SCM) market (SCM fills the performance gap between DRAM and NAND).

Sony says they chose ReRAM as its SCM because its memory cell can be made using advanced process technologies and a cross-point cell array can be used for it, making it easy to increase memory density.
