When it comes to RAM it’s never enough. If you have 512MB you need at least 1GB and when you have it, then the next step is 2GB. It’s like money. The more the merrier. Here is where MetaRAM comes into the picture. Apparently they’ve developed a new technology that can double or quadruple the performances of your DIMM RAM module.

How does MetaRAM work?

It uses a 3D chip stacking technology to put extra SDRAM chips onto a DIMM that will actually make it 2 or 4 times “bigger”. However these additions wouldn’t work without the secret recipe : some sort of custom chips that obviously work only on those custom designed circuits.

“We had to make our chip look like a DRAM to the memory controller, and like a memory controller to the DRAMs,” said Suresh Rajan, the MetaRAM co-founder.

MetaRAM also uses WakeOnUse technology that keeps all the SDRAM chips asleep until they are needed. This should help read and write times and of course will reduce power consumption to around 2.5 watts.

One of the company’s channel partners will soon announce a server that will be packed with 256GB (should allow up to 500GB) of main memory and the price is going to be under $50,000.

256GB is enough, right guys ?
