Answer» NEC develops memory that stores data without using power
Full Story...If this is economical, and can be mass produced Then:
1. Flash memory will bite the dust.
2. The Hard Drive makers will go crazy
3. You may never reboot your computer again.
4. Everything with change all over again.
This is big news. Others are picking it up.
That's what i posted....EXCEPT yours is a Forum link...clik mine for the article.Sorry, I had a DNS problem I revised my post.
That was a really great find, Patio.No problem...Wow! In addition to all the other great advantages this innovation would bring. For me personally it would allow me to once again leave a computer running all the time without concern for "time of day" hydro charges being a consideration. Since it was introduced in my Province my wife and i have dramatically altered our computer usage to conform to economic considerations. Hopefully it can be accomplished with a retrofit or add-on. truenorthThis development is a big change.
Years ago persistent memory was possible, but rather expensive. I recall playing with some RTC chips unmade by EPSON. The chip was a clock that was powered by ccells that mounted on top of the chip package. Int contains a 4000 byte memory that you could use. It could keep data for a couple of years just on the c little batteries. But it was static memory, not dynamic RAM. It was very expensive to make large megabyte arrays with static RAM. The idea never WENT beyond just a small am mount of CMOS memory.
The article in Patios link is about a type of memory that does not need any power to hold data values. Hard to grasp the concept. No power at all. Just power we you use it.
Time will tell if this new development can be WIDELY used. It will bring in a new way of using computers. When you are done, just turn off your computer. Or in will turn off by itself in you wait ten seconds. Maybe less. You will double the battery time of a laptop. If we still have laptops then.
Wow!!! *whispers* Lets go steal RAM out of computers.
Seriously? so i just take RAM out of someone's PC, then put it into my PC, then i have access to his bank account? Better with computers with more than one stick of RAM! Patio, You did a great search. That is good. Thanks.This is not RAM, it is CAM.
Random Access Memory
VS
Content Addressable Memory
Just had to add that...Well it is RAM, really. NEC just decided to call it something else.My old Itronix has persistent RAM, 16MB. It will hold contents for days with no power. TAM modules are proprietary. It was a $6000 laptop in 1994, bought it used for $40. Chassis (case) is magnesium.interesting. seems this technology would be more useful in flash drives and SSDs though. thanks for the link.

Maybe... but if u put data on a flash drive and plug it in two years later you still want it to be there...
Another thing, with CAM how does it choose what to " retian " or does it keep it all ? Problems SOLVED by clearing RAM by power-cycling may not be fixed with CAM instead of RAM.

Aside from the fact that any machine designed to use it in the same manner as DRAM will be designed to either clear it on startup or at the very least there will be a method of clearing it, much akin to the ability to open CD drives with a paper clip and "reset" phones and MP3 players.
