After 16 years of development approaching US Nantero to end mass production of NRAM (Non-volatile RAM), a flash and RAM contender built of carbon nanotubes. It is Fujitsu to produce a 55 nm chip with 256 MB of built-NRAM.
Fujitsu also plans clean NRAM memory chips with support for DDR4 and offer to integrate NRAM to its foundry customers.
Fujitsu NRAM writes “several thousand” times faster than flash and can withstand “thousands” of times more losses.
Nantero has previously told of her NRAM technology to withstand 800 ° C and survive for at least 10 years at 300 ° C. It can be read at 200 ° C and keep in memory at least a thousand years at 85 ° C. And so is the bit-addressable unlike the flash working in memory blocks.
At least five additional memory manufacturers will be producing NRAM. Some of them will produce in 28 nm and promise circuits on multiple Gbps with multiple bits per unit area than DRAM. Launches will come soon.
In addition, licensed the technology for further twelve companies. Possible application is to use them as a cache of processors and SSD memory.
