RAM (RRAM) is internal memory that can be used for PC and mobile devices.  Compared with the current flash memory, its reading and writing speed is much faster and more energy efficient. Today, California Crossbar, a technology company, announced that they have developed the new resistive RAM technology which can save 1TB  data in a single chip that is smaller than a stamp. It means that electronic products will greatly improve storage density in the future, meanwhile the RRAM writing performance is 20 times faster than the current best NAND chips, and the reading and writing power is only 1/20.

Depending on the device, RRAM can last battery life for weeks, months or even years. The using life is also 10 times longer than the NAND, it can be said it is a perfect high-speed memory. Crossbar also said that this memory can also be run as an array. They plan to license the technology to other companies, and now more than 30 patents have been granted.
