DRAM Manufacturers Ramp Up Production

[dimar]

I'd like to get RAM as much as my hard-drive. Once something is read from HDD, it would stay in RAM (until the next reboot), so HDD would never read the same thing twice, like a super cache So 1 or 2TB would be nice

Oh damn, does this mean I should be buying my 8GB modules for my PC now then?

You're over-simplifying it a little. Any changes made to data that's read from the hard drive would need to be written back to it, possibly re-read afterwards to reduce damage done from loss of power. If you have data loaded in DRAM that isn't on the hard drive or is in a different form from the copy on the hard drive and you lose power, you will be stuck with whatever is left on the hard drive because DRAM is volatile.

That means that it needs power running to it or it loses it's data, unlike HDDs, Flash, optical disks, and some other memory technologies. Technically, you can get a system with 1TB or 2TB of RAM, but it will cost a lot of money... There are quad CPU servers that support such memory arrangements. You can go to dell.com or other similar sites and look into the servers if you want proof. The 1TB arrangement is generally much cheaper than the 2TB, well under half the price, kinda like the price difference between 4GB and 8GB modules, except with 16GB and 32GB modules instead.

Sometime collusion is a good idea, if you want to keep the industry healthy, otherwise you will lose all but the ones that could survive and you end up with an unhealthy industry that is run by a single company and no competition.

Collusion is probably more thought of when it's done in a bad way, to ramp up profits to deplorable levels on all or almost all viable products for a certain function. It also means that the assorted companies involved need to be doing it in concert, under agreements (informal, illegal) to do it. Like you said, doing it or something similar can be good for an industry when it's products rapidly lose profit margins because of high supply and low demand. When we have DRAM selling so close to zero and even negative profits, there is a problem that needs to be solved.

Decreasing supply is a good solution because demand isn't really going to increase much, if at all. Decreasing supply allows stockpiled products to be sold out instead of added upon because the supply is increasing faster than demand. DDR3 has had a pretty long run and seems to have quite some time left before DDR4 comes out, so DRAM manufacturers have probably had it kinda hard because of the large amount of time (relative to the previous generations of system memory) that DDR3 has been going and will continue to go before the next DDR refresh with DDR4.
