Just as the graphene-based chips of the future are already being devised, now it is time to improve the memories that can be found in any computer today. A group of Russian and European scientists have been working on a new technology called 'T-rays' (terahertz radiation) that would improve RAM speeds by up to 1000 times.

'T-rays' (terahertz radiation) to improve the speed of RAM memories

The technology has been studied and is published by the scientific journal Nature Photonics. Terahertz or 'T-ray' radiation is not new, something similar is already used in airport scanners, but this time it would be applied to memory cells to alter their function.

What the scientists have achieved is to apply terahertz radiation to a ferromagnetic element with low coercivity, thereby managing to change the magnetic characteristics much more quickly. Applied to a RAM it could work (they estimate) up to 1000 times faster.

This would be a relatively 'cheap' response to improve the speeds of today's RAM, which improve over the years with new versions (DDR, DDR2 DDR3, DDR4, etc.) but not at the rate, for example, of cards graphics.

How could manufacturers do to implement this technology using a magnetic field on RAM? Today is a mystery
