Crossbar Resistive RAM stores a terabyte on a chip

<i>Crossbar believes it can write data to its chip at 140 megabytes per second, compared to 7 megabytes a second for flash. Read performance is 17 megabytes per second, with a random read latency of 30 nanoseconds.</i><p>The write performance sounds good, but the read performance seems very low. Also I don&#x27;t know where they get 7 megs per second for flash. Sounds like the picked the worst performer to compare to.<p>I&#x27;d be more impressed if they had something on the market.

&quot; It could also perform its storage functions at 20 times lower power, extending the battery life of devices using it to weeks, months, or years. &quot;<p>no, reducing RAM power 20x does not extend battery life of devices to weeks. Anything with a screen or active antenna will likely not see much of a difference

&gt; It can access that data 20 times faster than the best breed of flash memory<p>&gt; could also perform its storage functions at 20 times lower power<p>&gt; non-volatile<p>&gt; 10 times the endurance of NAND flash chips that it could replace<p>If this is true, wow, but I have a hard time believing it.

According to the wikipedia article on RRAM there are several companies working to bring this tech to market. <a href="http://en.wikipedia.org/wiki/Resistive_random-access_memory" rel="nofollow">http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Resistive_random-access_memory</a>

Does anyone know if there has been progress in volatile memory tech? I&#x27;m hoping for 1TB RAM chips with 10x faster access times than current RAM. It will enable PC gaming to deliver unmatched immersive experiences, among other applications.

Interesting to see that Samsung started mass production of their 3D NAND memory yesterday.<p><a href="http://www.engadget.com/2013/08/05/samsung-ships-first-3d-vertical-nand-flash/" rel="nofollow">http:&#x2F;&#x2F;www.engadget.com&#x2F;2013&#x2F;08&#x2F;05&#x2F;samsung-ships-first-3d-ve...</a>

This article makes a lot of extraordinary claims. Extraordinary claims require extraordinary evidence.<p>In this case, that means a reputable tech reporter from a reputable publication has to say &quot;this is the real deal&quot; before these guys can be taken seriously.<p>(I&#x27;m not doubting that they have any tech, it&#x27;s just that they seem to be promising something with no downsides, which in most cases means a marketing team has spun out of control.)

Given the graphic on the top a chip with 8 GByte at 77mm^2 I have no idea where they&#x27;re getting the &quot;Terabyte on a chip&quot; thing. Unless the mean a Terabyte on a 200 mm <i>die</i>?

I remember memristers were supposed to do something like this.<p>Anyone have an idea if this is related or unrelated.<p><a href="http://en.wikipedia.org/wiki/Memristor" rel="nofollow">http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Memristor</a>

maybe a more tech oriented article would have been preferable: <a href="http://www.theregister.co.uk/2013/08/05/crossbar_uncloaks_fast_tiny_capacious_rram_part/" rel="nofollow">http:&#x2F;&#x2F;www.theregister.co.uk&#x2F;2013&#x2F;08&#x2F;05&#x2F;crossbar_uncloaks_fa...</a><p>(venturebeat sounds like a investor magazine to me)

That is flipping amazing if true.<p>Also, that &quot;Crossbar Chip Design&quot; graphic made me chuckle. It is nearly meaningless by itself, and is placed so far away from the context it&#x27;s discussed in, it almost remains that way unless you&#x27;re trying to connect it.

How appropriate that this article and the following comic come out on the same day:<p><a href="http://thedoghousediaries.com/5275" rel="nofollow">http:&#x2F;&#x2F;thedoghousediaries.com&#x2F;5275</a> (Amazing Scientific Breakthroughs)

It&#x27;s nice to see memristors bearing fruit (or about to soon) finally.

Sad to think of the implications for the NSA.
