The makers of a new non-volatile RAM said the memory is ready to move from a prototype to a fabrication facility, where 1TB chips the size of a postage stamp will be produced and tested.

Silicon Valley start-up Crossbar expects some of its 3D Restive RAM (3D RRAM) products to be out in 2016 as memory in wearable devices, with high-density storage devices like solid-state drives arriving within 18 months after that.

RRAM starts out with an advantage over NAND flash, which has been approaching a density dead-end. RRAM is natively denser than NAND, with higher performance and endurance. The best NAND products today have 100,000 erase-write cycles. Crossbar’s 3D RRAM can sustain 100 million write cycles, according to Sylvain Dubois, Crossbar’s vice president of marketing and business development.
