IBM teams with Infineon, Macronix on replacement for flash memory chips
IBM on Monday announced that it was working with Infineon Technologies and Macronix International to develop memory technology that could in the future replace flash memory chips in computers and portable storage devices.
Phase-Change Memory (PCM) technology uses a special material, called phase-change material, to store memory data. It can change its structure from an amorphous to a crystalline state by using electrons to pass energy through the material, said Chung Lam, manager of the PCM project at IBM.
Computer memory stores data in the form of zeros and ones. With PCM technology, the material's state represents this information, with an amorphous form, or indefinite structure, representing 0 and a crystalline, or definite, structure representing 1.
PCM offers several advantages over flash memory technology, including greater reliability, Lam said. It does not use floating gates, which flash memory chips use to store information. This makes PCM faster and more reliable. "It is more reliable because there are no moving parts involved like in flash memory. We can change the status [of material] without floating gates," he said.
Flash memory uses floating gates to store electrons, which represents the binary data. With PCM, resistors are used instead of floating gates, he said.
"Floating gate stores a large number of electrons. More than a thousand electrons [in flash memory] represent one state of binary. In PCM, the resistance of the material represents the binary data. PCM stores 1 and 0 in the state of material," Lam said.
PCM will provide quicker read and write capabilities than flash memory, Lam said. In PCM, "you can directly write without erase. In flash memory, you need to erase before you can write," he said. Even if the device containing PCM is shut down, the memory retains data, making it nonvolatile memory. Flash memory is also a non-volatile memory type.
Research on the technology is in its early stages, and PCM could hit the market in three to five years, Lam said. "We are looking at it as a research project, whether we can actually make any memory as [fast] or faster than flash memory," he said. It could be used in products ranging from servers to consumer electronics, according to the company.
IBM has in the past worked with Germany-based Infineon Technologies on memory technologies, Lam said. Taiwan-based Macronix brings in manufacturing expertise, he said.
Twenty to 25 employees from the three companies will be dedicated to the PCM research, which will be conducted at IBM's research centers in Yorktown Heights, New York, and San Jose, California, according to IBM.
I think this article shows us that computer technalogiy developing in right way!! and im very glad of that, i like very thing touching on ITs!! and it was good news for me when i read it!!!
Notice from WeaponX:
Use quotes next time. This is basically a copy (for the most part) of the entire article.
nice, I can't wait until they actually get this chip into the market. If its also possible to make the storage capacity high enough, I hope it also replaces clunky hard drives.

Did not see the delay. If you can't wait, and have to wait some tens of years...
@yordan: It's in Russian. I kinda figured it out by looking at the original poster's email address.
It says .ru, so it's Russia.
EDIT: whoops, sorry Yordan, I accidentally deleted ur post because it doubled. The system registered it as one post. EDIT2: the post was a spammer's post in Russian. Deleted.
This PCM technology sounds fine from that... But there's no mention on the storage density. How much storage space can they pack in a say compact flash sized card? Or is the speed this technology's only forte? And what about the production costs? Flash memories have been on the market for awhile and there's a huge demand and huge production numbers for them, which has dropped their price a lot. Can we expect this kind of technology have chance in the markets if it will cost multiples of the flash memory prices.
Sorry for my sceptism, actually I think this is good news. I believe this technology could have lot of uses with mobile phones for example. The current phones using flash memory are somewhat suffering from the slowish speed of the memory.
xboxrulz, could you remove all the off topic posts in this thread. Including the discussion of "offtopic" and spam.
what I would personnally like to know is, how many times a structure change from amorphous to cristalline stat can occur. This means - how long will such a device be able to work ? Remember, how long a CDR-W can work and reman erasable - not so many times, indeed, compared to the number of times you write down and erase files on your hard drive. So, flascards are used as disk drives today. would yo like to see your flashcard endup behaving like a CD-ROM, ending like a scratched CD ?
This is for people that use firefox. It apparently works on all versions of Firefox, but I have only
tested it on Firefox 3. Now, what this does: This program reduces the amount of memory that firefox
uses. So, when I load firefox, it takes up about 30k of memory. When this program loads, it only
takes a max of 1.5k. It also only takes max of 1k memory to run this little program. That's 28k
you get to use elsewhere. It's a very handy program for reducing memory. Download Link: CODE

I have been using the picking tool with setShapeCylinderSegment (this returns infinit results but

Google to see the problem and apparently it is caused a memory leak. I have tried to solve it by
simply setting all the variables to null after they are used but this doesn't help. Is there
something I can do to or a free software I can use to find the exact variable that is causin....

store other computer files. Everything was going fine until one day I plugged it into my pocket
drive and tried to put a text file onto the card to give to a friend. A message came up "Access

Newer drives intentionally lower the armature/actuator speed to decrease noise, which can sometimes
affect drive performance, but to be honest, I kind of miss hearing the click-click-click of the days

failing; the noise produced by most hard drives is meaningful and useful.

Hello. Recently, I upgraded the memory on my computer. Previously it had 192mb, and I added 256mb. I
installed the RAM properly: it works fine, but it seems that it is now only recognizing the 256mb
RAM chip, and ignoring the 192mb (two chips). E.g. when I go to the system menu (Win XP), it only
says 256mb of RAM, but when summed it should be 448mb. Is this normal? Is there a way to fix it?
Thanks in advance.....

with information about the course you are going to play. It could produce all sorts of information
about the course including details about each hole, various slopes for the hole as well as the green
and possibly a map of each hole. The amount of data that could be stored is huge and golfers will
love it because they always like to use stats! Also, it can be combined with i....

Ever since I picked up my Palm TX last Winter, I've noticed the ever decreasing size of memory
cards especially with SD (Secure Digital). My Palm TX has a port of SD cards which is great. It
can handle anything from 256mb to 2gigs. If you have ever since the size of an SD card, then you
know that it is pretty small. It can pack a whole lot of data in a small amount of space. Now
after SD comes miniSD. I don't have anything that uses them, but I know they are pretty small.
Some of the older model mobile phones use miniSD cards for expansion memory. Finally....
