Lest anyone forget that Samsung dabbles in more areas than just displays, the technology guru has just begun sampling what it claims is the world's first 16GB double data rate-4 (DDR4), registered dual inline memory modules (RDIMMs), which at the outset are designed for use in enterprise class servers.

Samsung said it's sampling both 8GB and 16GB DDR4 memory modules, which it produces using a 30nm-class process technology. These aren't the first DDR4 modules, however, as Samsung unveiled 2GB DDR4 memory sticks way back in December 2010.


"By launching these new high-density DDR4 modules, Samsung is embracing closer technical cooperation with key CPU and server companies for development of next-generation green IT systems," said Wanhoon Hong, executive vice president, memory sales & marketing, Samsung Electronics. "Samsung will also aggressively move to establish the premium memory market for advanced applications including enterprise server systems and maintain the competitive edge for Samsung Green Memory products, while working on providing 20 nanometer (nm) class based DDR4 DRAM in the future."

According to Samsung, DDR4 technology offers the best performance out of all memory products currently available, and it's expected to reach twice the current 1,600Mbps throughput of DDR3 by next year. DDR4 modules also require just 1.2 volts, reducing power consumption by about 40 percent compared to DDR3 memory operating at 1.35V.

As of right now, there doesn't exist a finalized JEDEC standard for DDR4, though Samsung is confident an official specification will be hammered out by August.

I think you mean "1,600MHz effective clock speed" instead of "1,600Mbps". Currently DDR3-1600 is transfering at 12,800MB/s or 102,400Mbps.

I was worried until I saw that the corners of the module weren't sufficiently rounded that Apple could reasonably be expected to be able to convince a judge to accept that the design violates a valid patent held by that company. But, giving the state of the patent and the judicial system in the United States, Samsung should be aware that being able to sell its modules in that country is not a given....

1600Mbps (which is a per pin rating), as stated in the press release, is correct.

Here one has to distinguish between the transfer rate, e g, 1600 MT/s, which refers to the number of operations that transfer data in each data-transfer channel, and the peak transfer rate, e g, 12800 MB/s, which is the bit rate at which binary data is transferred, and which is not only dependent upon the transfer rate, but on the width of the channel, i e, with a data bus 8 bytes wide, the data rate would be 8 bytes x 1600 MT/s = 12800 MB/s....
