Forget Flash: Resistive RAM Crams 1TB Onto Tiny Chip

nk497 writes "Flash memory could soon be a thing of the past, according to U.S. startup Crossbar, which claims it's close to bringing resistive RAM (RRAM) to the market. Crossbar is touting impressive specs for the RRAM technology, promising 20 times the write performance at a fraction of the power consumption and size of the current best-in-class NAND flash modules — and squeezing terabytes of storage capacity onto a single chip the size of a postage stamp. The company also claims its technology can retain data for up to 20 years, compared with the standard one to three years with NAND flash."

      Early Computers did all the work. You had a computer it did all the work for you and only you.
      Then we got the mainframe One Big computer with terminals so people use the terminals and the data gets saved on the Mainframe(s).
      Then came the PC, we started to move off the mainframe and ran programs directly on our computer again.
      Once broad band became cheap enough and popular services began to move to the cloud as on the average your data was safer there, and easier for the company to manage the software.
      So with cheap and a lot of data we could go back to more of a Personal computing role again. Probably keeping the strong points from the past and making using computing a little more different.

      Say you now have a Netflix app that will in the background download what it expects you to watch. Then if you want to watch it it is available even if it is offline.
      Or your system will host an archive of your data in cases your networks speed is too slow or are offline.

But to get the optimal conveniences we are trading off Slower CPU, and Storage to get small form factor at a good price. So many apps are popular on the cloud. Because the servers have the Big CPUs and storage and will just send output to the low end Tablets. Now these tablets are getting faster and more storage so people will want to run more apps on them, thus more apps will be created.

    Listen to physicians dictate some time, particularly pathologists or radiologists who tend to do a lot of it. Yes, they often do speak very quickly - 200+ words per minute is not rare. Once they get good at it, they can easily rattle off a report in far less time than they could possibly type it no matter how quickly they type. Transcriptionists normally have to slow the recording down while typing to get what is being said. It's very easy to talk faster than anyone can type. Takes some practice to do so in a useful manner though. Helps too if there is some consistency in what is being said - like if you have to produce a consistent type of report. Lawyers and doctors very often use dictation systems to good effect and they do it 100% because it saves time, even for good typists.

    The issue I have with believing this is not the forming complete sentences before speaking, but the simple fact that speech is slow and error prone.

    Not once you are used to dictating. With a proper dictation system you can easily start, stop and record over what you've already done if you make an error. (People make a lot of errors typing too) Typically you get the report sent back to you for review and correction after transcription. However even including review it is still usually faster than typing it yourself.

My favorite was when he was mocking Apple having the one button mouse and then one upped that by saying the kinect was "like a 0-button mouse."

    My main argument would probably be, when you have a physical key/button with tactile feedback you can much more easily ensure an intentional action on the part of the user. Whereas touchscreens you are much more prone to fat fingering the wrong key (although this happens sometimes on keyboards too to be fair, just not nearly as often in my experience). A promising tech I remember reading about I think on slashdot was the touchscreen that could bend in such a way as to give tactile feedback at any point of the screen for a variety of sizes and shapes. Arguments could still be made to have solid keys/buttons still, but brings the two a little closer together at least.

Can we please get cheap bootable PCIe x4/x8 cards instead of SATA. And stop making PCIe cards that are nothing more than SATA RAID + SATA SSD's. Design an ASIC that looks like an ATA or SCSI controller and directly talks to the memory and PCIe bus. If a 1 terabyte PCI card which has at least 2GB sec read speed for around $300 came out I would buy it immediately on impulse. I want to jump into a game and not even realize its loading. I want my programs to simply pop up. I want to forget that there is a difference between main memory and storage speeds.

    At that point I won't have to worry about space limits on my SSD and eliminate the need for mechanical storage for non critical stuff like multimedia, backups, archives etc. That is how I do it today, one 256GB SSD for just my games, 1TB for boot/programs/VM's etc. I also use a 2TB eSATA drive for extra stuff when I ran out of room on my 1TB (too many experimental VM's). A high capacity SSD would allow me to stop juggling which games I have installed on my SSD.
