Please correct my maths
But doesn't 9.4 mW/bit equate to just over 10 MegaWatt per Gigabit or about ~ 1.25 MW/GByte?
We're gonna need a bigger power cable....
NEC has claimed to have come up with the World's first memory cell to use new form of storage that's as quick as Ram yet as non-volatile as Flash. The memory - co-developed with Japan's Tohoku University - is based on 'spintronics' technology: kit that utilises electrons' rotational characteristics and their resulting ability …
You are assuming 1Cell = 1Bit
You may be correct, but I highly doubt it... This is arguably an early implementation of Quantum Tech... and previous news stories have talked about the possibility of using this tech not just to store binary on/off 1/0 values, but much more.
Even being able to store values between 0-255 per cell (8 bits binary equiv) brings the power consumption down to a much more manageable 10 MW/Gig ;-)
Anyhoo... the cell doesn't require power at all times - only when reading and writing.
