Non-volatile memory technology is now at a turning point where we find out which technology will be doomed to be BETAMAX and which will carry on to become the VHS equivalent; hopefully that analogy is not too accurate as VHS was not the better of the two. Allyn discussed the reasons why the market is looking for a new technology back in 2012 and his predictions that NAND still had some life in it have been proven over the past few years but we are seeing new limitations with the current technology.
In the past we have covered HP's Resistive RAM, also called a Memrisitor, which has been in development for many years but has finally appeared in some Panasonic microcomputers which control sensors. STT-MRAM, spin transfer torque magnetoresistive random access memory, is Toshiba's project and while we still haven't seen any product it has been in development for more than 3 years and news of prototypes should arrive soon. Lastly is NRAM, nano-RAM so named for the use of carbon based nanotubes in its design which is being developed by Nantero.
It is Nantero which is in the news today, having secured $31.5 million in funding this year, triple what they have seen in previous years according to the numbers The Inquirer has. This particular technology offers densities in the terabytes per chip, storage which requires no active power source once written to and data retention of over 1,000 years at 85 degrees Celsius. The speeds should match those expected from STT-RAM but at a fabrication price closer to the much lower cost RRAM; don't hold off buying your next SSD but do not think that market is going to get boring any time soon.
"It got $31.5m in an over-subscribed round to continue developing its nanotube-based non-volatile RAM (NRAM) semiconductor technology, which it says has DRAM read/write speed and is ultra-high density – think terabits."
