Newly revealed Resistive RAM (RRAM) tech puts 1 TB of storage on one chip

The amount of storage that can be put into a smartphone or PC could be set to increase at a rather rapid rate, and bring with it some boosts in battery life as well. That's due to some new technology that's being announced today by the Santa Clara, California company called Crossbar.
Today's press release reveals what Crossbar calls Resistive RAM (RRAM) that they claim will put 1 TB of storage on a single chip that's smaller than a postage stamp. In addition, several RRAM chips can also be stacked on top of each other, as shown in the illustration above, which allows for several terabytes of storage to be put in place in an electronic product.
Crossbar says RRAM will have write performance that's 20 times faster than the current best NAND Flash memory chip. It will also use 20 times less power, which the company claims could extend the battery life of a device by weeks, months or even years, depending on the product. RRAM also is supposed to have 10 times the endurance of NAND Flash memory, and with half the die size.
Crossbar claims that it has already made a memory array at a commercial fabrication facility. It plans to sell RRAM products themselves and will also license the technology to other companies. It has been granted 30 patents on the technology so far.
