Crossbar: RRAM will have twice the density of NAND for the same cost

Earlier this week, we reported on an announcement by Crossbar, a new technology startup that said it has come up with what it calls Resistive RAM (RRAM). Crossbar claims that RRAM will be able to handle 1 TB of storage on one chip, and stack several of those chips on top of each other. It also claims that it will have 20 times the write performance of current NAND flash storage, along with 20 times less energy use.

Some people in our news comments wanted to know the cost of RRAM because of its new manufacturing process. We contacted Crossbar and received this statement from their PR representative:

We are not disclosing cost as that has not been determined. It depends on a variety of factors, applications, volumes, etc. However, our technology has a much better area efficiency and better performance than NAND. Crossbar will be able to provide, for the same cost, twice the density of NAND with much better performance.

Prices for NAND Flash storage tend to fluctuate based on supply. The DRAMeXchange.com website claims that currently a 64 Gbit NAND flash chip is priced at $7.50. As far as when we can expect to see RRAM storage in products such as SSDs and in smartphones, Crossbar indicated it might take a little while. It told Neowin:

Currently, we are in discussions with foundries. Over the next 2-3 years we'll be rolling out solution starting with embedded, then standalone Crossbar product and finally move into the IP licensing stage.

With the sales expansion of smartphones, combined with the growing use of SDDs in laptops and even desktop PCs, it's safe to say that we will see huge storage space increases in these products in the next few years.

So for $7.50 you would get 128GB of storage with better performance. Would that be roughly correct or am I seeing this wrong?

Yes unfortunately. 64 Giga*bits* is 8 Giga*Bytes*, so you need 16 chips for a 128GB drive which is $120 at the price quoted without factoring in the other hardware costs.

They seem to be referring to current NAND though so could see that significantly reduced with the new tech,.

Ah, indeed, GBit, I missed that! So for $7.50 we would get a 16GB chip. A 128GB chip would cost $60 with the new RRAM technology. That's an OK price for brand new technology, I guess.

No more than two years of waiting should be perfectly awesome. But i won't really think they can make it after that kind of response. Can we even get to see a demo of RRAM performance?
