The hunt for memory technology to replace NAND flash storage within the next 10 years is under way, and startup Crossbar is planning to bringing its version of RRAM (resistive random-access memory) technology to market next year. RRAM, a form of nonvolatile memory that is not available commercially yet, will be cheaper, smaller and more power-efficient than NAND flash, which is being used in solid-state drives and mobile flash drives, said Tanmay Kumar, vice president of device engineering at Crossbar.
