Invented by Professor Manus Hayne from the Physics Department at Lancaster University, ULTRARAM combines the high performance of dynamic random-access memory (DRAM) with the non-volatility of flash, something that until now was widely believed to be unachievable.
The technology has the ability to both store data for more than 1,000 years – exceeding the capabilities of flash, and also to be read from and written to very quickly and at lower energy than DRAM.
Similar to a compound semiconductor version of flash, ULTRARAM exploits the quantum-mechanical effect of resonant tunnelling, replacing the oxide tunnel barrier in flash with a triple-barrier resonant tunnelling structure. This eliminates flash’s deficiencies, allowing a floating-gate memory to operate at low voltage and high speed, with high endurance and unprecedented efficiency, but without compromising on non-volatility.
Quinas’ commercial objective is to develop the technology into a product that can out-perform DRAM, the working memory in digital electronics and computing, with the significant added advantage of non-volatility.
“New forms of memory tiering technology can potentially create compelling value for customer workloads in the future,” said Jay Kramer, Chair of the Awards Program and President of Network Storage Advisors. “This is a new type of computer memory which combines speed, endurance, retention and energy efficiency into a single memory concept.”
Commenting on the award James Ashforth-Pook, CEO of Quinas Technology said, “Quinas is delighted to have been honoured with this award by Flash Memory Summit. It is particularly gratifying to have this endorsement from the world’s leading memory conference, given the highly disruptive use of compound semiconductors in ULTRARAM.”
The Flash Memory Summit award is given for ’innovations that will change the way flash memory and all other forms of high-performance memory work, and how it is used in products. The recipients of this award will enjoy significant differentiation of their intellectual property and patents from alternative competitive technologies in the memory industry’.
