UltraRAM Secures £1.1 Million to Revolutionize Computer Memory
Quinas Technology, a UK-based startup, has received a significant boost in its quest to bring a groundbreaking memory technology to market. The company has secured £1.1 million ($1.43 million) in funding from Innovate UK to accelerate the development of UltraRAM, a revolutionary memory solution that promises to combine the best features of both RAM and storage.
What is UltraRAM?
UltraRAM is a non-volatile memory technology developed by researchers at Lancaster University and the University of Warwick. It aims to offer:
- The speed and energy efficiency of DRAM
- The non-volatile data retention of NAND flash storage
- Unprecedented durability with up to 10 million rewrite cycles
- Extraordinary data retention, capable of holding information for over 1,000 years without power
The Technology Behind UltraRAM
At its core, UltraRAM utilizes quantum resonant tunneling, a principle commonly used in photonic devices like LEDs and laser diodes. The memory cells are constructed using compound semiconductor layers of GaSb, InAs, and AlSb, which are precisely deposited using advanced epitaxy techniques.

From Lab to Fab: Scaling Up Production
The primary goal of the Innovate UK-funded project is to scale up UltraRAM production:
- Increase wafer sizes from 75mm to 150mm
- Transition from molecular beam epitaxy (MBE) to metal-organic chemical vapor deposition (MOCVD)
- Develop larger memory arrays and reduce individual device sizes
- Aim for eventual production on 200mm wafers
Market Potential and Future Applications
James Ashforth-Pook, CEO of Quinas Technology, highlighted the significant market opportunity:
The global memory chip market is estimated to be worth about $320 billion by 2030. UltraRAM's unique combination of non-volatile storage and rapid access memory addresses many emerging needs in AI, quantum computing, defense, and aerospace applications.
Environmental Impact
Beyond its technical capabilities, UltraRAM has the potential to significantly reduce energy consumption and carbon emissions in computing systems across various scales.
Challenges Ahead
While UltraRAM shows immense promise, the road to mass production is not without obstacles. The technology's complex design and the need for specialized manufacturing facilities present significant challenges. However, with this latest funding and support from IQE, a leading British semiconductor firm, Quinas Technology is well-positioned to overcome these hurdles.
As the project progresses, the tech world will be watching closely to see if UltraRAM can deliver on its revolutionary promises and potentially reshape the landscape of computer memory.
