As the world leader in carbon nanotube electronics, Nantero, founded in 2001, has developed a new generation of memory called NRAM™ (non-volatile random access memory) that can enable a variety of exciting new features and products in both consumer and enterprise electronics. This new super-fast, ultra-high density memory can replace both DRAM and flash in a single chip, or enable new applications as a storage class memory, while also delivering the low power, high speed, reliability, and endurance needed to drive the next wave of electronics innovation.

who's who in SSD? - Nantero

by Zsolt Kerekes, editor - - June 2015

I created a listing for Nantero here on in 2006 - because like other nvm related companies I had a gut feeling they would one day have something to offer for the SSD market.

It was 9 years later. however, in 2015 - when Nantero next came into my radar - due to a funding related press release.

At the limits - Nantero's memory technology has some unique characteristics which make it interesting in at least 2 markets.
  • military SSD market - re military and space applications - Nantero says its memory "NRAM was successfully launched in a NASA Space Shuttle where it performed reliably even under bombardment by intense radiation. and among other things has ...extremely low power consumption."

I've been looking at different aspects of power loss data integrity schemes in mission critical non volatile memory systems for over 30 years.

But every time I revisit this vast topic and compare fresh examples from the market - I learn something a little bit new.

My blog - Zero to three seconds - demonstrates the extreme range of hold up times now in the market inside leading edge 2.5" military flash SSDs. the article

Nantero has amassed $110 million funding for NRAM
Editor:- December 8, 2016 - Nantero today announced the closing of an over $21 million financing round bringing the total invested in the company to over $110 million.

Nantero currently has more than a dozen partners and customers in the consumer electronics, enterprise systems, and semiconductor industries actively working on NRAM. The new funding will enable the company to support these partners in bringing multiple products into the market, while also enabling new customers to begin development.

A later blog - NRAM set to spark a 'holy war' among memory technologies (January 12, 2017 on ComputerWorld) discusses the 16 years history of NRAM and quotes a report from BCC which said that NRAM now has the potential for mass customization.

Nantero gets $31 million funding for 300º C retention nvram
Editor:- June 2, 2015 - Nantero today announced a $31 million Series E financing round for its NRAM technology which the company says is scalable to below 5nm and which has >1,000 years retention at 85º C or more than 10 years at 300º C.

Editor's comments:- Nantero was founded 14 years ago, and the last time I wrote about them was in 2006.

But the size and educational sophistication of the SSD ecosystem today means that designers (and investors) can appreciate the nuances of difference which might be useful in extreme boundary applications.

Offering a scalability roadmap below the current commercial limits of flash, and ruggedness way beyond flash - Nantero's technology has attractive features which might lure SSD designers out of their 40 year comfort zone of trapped charges in semiconductor cells.
