Resistive random-access memory (ReRAM) is a promising new technology. A number of different companies are developing this new technology. Resistive Random Access Memory (RRAM/ReRAM) is a new type of memory designed to be non-volatile. ReRAM has a great potential for high storage density, greater read and write speeds, lower power usage, and cheaper cost than flash memory. Due to limits of the materials flash memory Flash memory cannot continue to scale and will be replace by ReRam devices. More detailed information can be found here.
