New RRAM memory promises a terabyte of storage on a stamp-sized chip
Californian start-up Crossbar unveiled new chip twenty times faster than previous flash storage
Californian-based start-up has announced a new memory chip for next-generation electronics. Crossbar’s Resistive RAM (RRAM) is capable of storing a terabyte of data (equivalent to 250 high-definition movies) on a chip the size of a postage stamp.
RRAM is a new type of non-volatile memory (meaning it stores data even when it’s not being powered) that is twenty times faster than the fastest current flash memory. Crossbars says that it can write data to its chips at 140 megabytes a second, compared to 7 megabytes a second for flash.
“Non-volatile memory is ubiquitous today, as the storage technology at the heart of the over a trillion dollar electronics market – from tablets and USB sticks to enterprise storage systems,” said chief executive officer George Minassian in an official statement.
“With our working Crossbar array, we have achieved all the major technical milestones that prove our RRAM technology is easy to manufacture and ready for commercialization.”
Crossbar’s confidence in its product has so far been matched by investors, with the company raising $25 million in venture capital. These backers include the prestigious Kleiner Perkins Caufield & Byers, who invested heavily in both Google and Amazon before the companies became multi-billion success stories.
The company plans to create its own chips and sell them to the market but will also licence its technology to other vendors. Although it will take a lot of momentum to replace the current flash memory standards, the chips would offer significant increases in memory – putting terabytes of storage on smartphones and tablets.
The new RRAM technology could also prove useful for power the internet of things and wearable technology, as it uses twenty times less power and has ten times the endurance of current NAND flash chips. This would make for devices that lasted longer without a breakdown in memory and that wouldn’t require constant charging
