Startup memory firm Crossbar is to detail new developments in its Resistive RAM (RRAM) technology, which promises to deliver a terabyte of storage on a single chip, at the Flash Memory Summit in California next week.
Crossbar, which emerged from stealth mode last year, is to discuss its RRAM technology in three presentations during next week's Flash Memory Summit 2014 in Santa Clara. As well as new developments in the technology, these will cover topics such as the applicability of RRAM to new markets including the Internet of Things (IoT), the firm said.
The company had already disclosed some details of its technology, which enables a simple memory cell structure formed by a switching medium sandwiched between the crossbar junctions of electrodes arranged in a grid fashion.
Applying a voltage enables the medium to be set or reset to store binary digits, enabling it to be used for high-performance non-volatile storage that is claimed to be able to scale to deliver high densities.
In June, Crossbar announced it had demonstrated pre-production 1MB arrays, and said these represented a critical milestone toward commercialising terabyte-scale memory arrays on a chip the size of a postage stamp.
These arrays are based on what Crossbar calls 1TnR Selectivity technology, which stands for 1 Transistor driving n Resistive memory cells. This will be discussed at the Flash Memory Summit, according to the firm.
In a statement, Crossbar chief executive George Minassian said that firm had broken through traditional boundaries with its latest developments.
"With 1TnR, companies will realise the dream of extremely dense, highly reliable, and high-performance solid-state storage. It's truly ground breaking and has the potential to redefine what's possible in enterprise storage and high-capacity non-volatile system on a chip (SoC) memories," he said.
Crossbar still claims that the RRAM technology will enable it to deliver capacities of up to 1TB per chip, with 20 times the write performance of existing Nand flash technology and 10 times the endurance.
The relevance to the Internet of Things is that RRAM should easily integrate into an SoC to provide non-volatile storage that can operate for years without a battery change, according to Crossbar.
The firm said it is currently finalising agreements with several global semiconductor companies and plans to announce the first licensing agreements in the near future.
