    Is the age of ReRAM upon us?

    Toshiba invented NAND flash twenty five years ago. Today, flash memory is used in iPhones and iPads, and a myriad of mobile gadgets used by hundreds of millions of people -- at least -- around the world. Still a leader in flash memory, Toshiba continues pushing forward. The company recently received a patent for a ReRAM device that may soon replace both NAND flash and DRAM. ReRAM (or RRAM, for resistive random-access memory) is a non-volatile memory type developed independently by several companies, including Toshiba, HP and others.
    The market for ReRAM is heating up. In January, Japanese firm Elpida publicly claimed it had a working ReRAM prototype that was capable of switching state at 10 nanoseconds -- the equivalent to DRAM. The company is working with Sharp to develop ReRAM chips for commercial use in 2013, although this may be impacted by persistent reports that the financially strapped Elpida will merge with Micron Technology. Numerous other companies are similarly building out their capabilities for ReRAM. Sony, Samsung, Panasonic, Micron and others are working to commercialize ReRAM. According to the EE Times, SanDisk recently let slip its interest in ReRAM by placing a job ad on its website for a ReRAM expert. Panasonic recently announced plans to go into production of ReRAM chips and HP has stated their intention to develop ReRAM-based products within the next couple of years.
